GFile is a high level abstraction for manipulating files on a virtual file system. GFiles are lightweight, immutable objects that do no I/O upon creation. It is necessary to understand that GFile objects do not represent files, merely a handle to a file. All file I/O is implemented as streaming operations (see GInputStream and GOutputStream).
To construct a GFile, you can use:
g_file_new_for_path() if you have a path.
g_file_new_for_uri() if you have a URI.
g_file_new_for_commandline_arg() for a command line argument.
You can move through the file system with GFile handles with
g_file_get_parent() to get a handle to the parent directory.
g_file_get_child() to get a handle to a child within a directory.
g_file_resolve_relative_path() to resolve a relative path between
two GFiles.
Many GFile operations have both synchronous and asynchronous versions
to suit your application. Asynchronous versions of synchronous functions
simply have _async() appended to their function names. The asynchronous
I/O functions call a GAsyncReadyCallback which is then used to finalize
the operation, producing a GAsyncResult which is then passed to the
function's matching _finish()
operation.
Some GFile operations do not have synchronous analogs, as they may
take a very long time to finish, and blocking may leave an application
unusable. Notable cases include:
g_file_mount_mountable() to mount a mountable file.
g_file_unmount_mountable() to unmount a mountable file.
g_file_eject_mountable() to eject a mountable file.
One notable feature of GFiles are entity tags, or "etags" for short. Entity tags are somewhat like a more abstract version of the traditional mtime, and can be used to quickly determine if the file has been modified from the version on the file system. See the HTTP 1.1 specification for HTTP Etag headers, which are a very similar concept.
typedef struct _GFile GFile;
A handle to an object implementing the GFileIface interface. Generally stores a location within the file system. Handles do not necessarily represent files or directories that currently exist.

void (*GFileProgressCallback) (goffset current_num_bytes, goffset total_num_bytes, gpointer user_data);
When doing file operations that may take a while, such as moving a file or copying a file, a progress callback is used to pass how far along that operation is to the application.
|
the current number of bytes in the operation. |
|
the total number of bytes in the operation. |
|
user data passed to the callback. |
gboolean (*GFileReadMoreCallback) (const char *file_contents, goffset file_size, gpointer callback_data);
When loading the partial contents of a file with g_file_read_partial_contents(),
it may become necessary to determine if any more data from the file should be loaded.
A GFileReadMoreCallback function facilitates this by returning TRUE if more data
should be read, or FALSE otherwise.
GFile* g_file_new_for_path (const char *path);
Constructs a GFile for a given path. This operation never
fails, but the returned object might not support any I/O
operation if path is malformed.
|
a string containing a relative or absolute path. |
Returns : |
a new GFile for the given path.
|
GFile* g_file_new_for_uri (const char *uri);
Constructs a GFile for a given URI. This operation never
fails, but the returned object might not support any I/O
operation if uri is malformed or if the uri type is
not supported.
|
a string containing a URI. |
Returns : |
a GFile for the given uri.
|
GFile* g_file_new_for_commandline_arg (const char *arg);
Creates a GFile with the given argument from the command line. The value of
arg can be either a URI, an absolute path or a relative path resolved
relative to the current working directory.
This operation never fails, but the returned object might not support any
I/O operation if arg points to a malformed path.
|
a command line string. |
Returns : |
a new GFile. |
GFile* g_file_parse_name (const char *parse_name);
Constructs a GFile with the given parse_name (i.e. something given by g_file_get_parse_name()).
This operation never fails, but the returned object might not support any I/O
operation if the parse_name cannot be parsed.
|
a file name or path to be parsed. |
Returns : |
a new GFile. |
GFile* g_file_dup (GFile *file);
Duplicates a GFile handle. This operation does not duplicate
the actual file or directory represented by the GFile; see
g_file_copy() if attempting to copy a file.
This call does no blocking i/o.
guint g_file_hash (gconstpointer file);
Creates a hash value for a GFile.
This call does no blocking i/o.
|
gconstpointer to a GFile. |
Returns : |
0 if file is not a valid GFile, otherwise an
integer that can be used as hash value for the GFile.
This function is intended for easily hashing a GFile to
add to a GHashTable or similar data structure.
|
gboolean g_file_equal (GFile *file1, GFile *file2);
Checks equality of two given GFiles
This call does no blocking i/o.
char* g_file_get_basename (GFile *file);
Gets the base name (the last component of the path) for a given GFile.
If called for the top level of a system (such as the filesystem root or a uri like sftp://host/ it will return a single directory separator (and on Windows, possibly a drive letter).
This call does no blocking i/o.
char* g_file_get_path (GFile *file);
Gets the local pathname for GFile, if one exists.
This call does no blocking i/o.
char* g_file_get_uri (GFile *file);
Gets the URI for the file.
This call does no blocking i/o.
char* g_file_get_parse_name (GFile *file);
Gets the parse name of the file.
A parse name is a UTF-8 string that describes the
file such that one can get the GFile back using
g_file_parse_name().
This is generally used to show the GFile as a nice string in a user interface, like in a location entry.
For local files with names that can safely be converted to UTF8 the pathname is used, otherwise the IRI is used (a form of URI that allows UTF8 characters unescaped).
This call does no blocking i/o.
GFile* g_file_get_parent (GFile *file);
Gets the parent directory for the file.
If the file represents the root directory of the
file system, then NULL will be returned.
This call does no blocking i/o.
GFile* g_file_get_child (GFile *file, const char *name);
Gets a specific child of file with name equal to name.
Note that the file with that specific name might not exist, but you can still have a GFile that points to it. You can use this for instance to create that file.
This call does no blocking i/o.
GFile* g_file_get_child_for_display_name (GFile *file, const char *display_name, GError **error);
Gets the child of file for a given display_name (i.e. a UTF8
version of the name). If this function fails, it returns NULL and error will be
set. This is very useful when constructing a GFile for a new file
and the user entered the filename in the user interface, for instance
when you select a directory and type a filename in the file selector.
This call does no blocking i/o.
gboolean g_file_contains_file (GFile *parent, GFile *descendant);
Checks whether parent (recursively) contains the specified descendant.
This call does no blocking i/o.
char* g_file_get_relative_path (GFile *parent, GFile *descendant);
Gets the path for descendant relative to parent.
This call does no blocking i/o.
GFile* g_file_resolve_relative_path (GFile *file, const char *relative_path);
Resolves a relative path for file to an absolute path.
This call does no blocking i/o.
gboolean g_file_is_native (GFile *file);
Checks to see if a file is native to the platform.
A native file s one expressed in the platform-native filename format, e.g. "C:\Windows" or "/usr/bin/". This does not mean the file is local, as it might be on a locally mounted remote filesystem.
On some systems non-native files may be available using
the native filesystem via a userspace filesystem (FUSE), in
these cases this call will return FALSE, but g_file_get_path()
will still return a native path.
This call does no blocking i/o.
gboolean g_file_has_uri_scheme (GFile *file, const char *uri_scheme);
Checks to see if a GFile has a given URI scheme.
This call does no blocking i/o.
char* g_file_get_uri_scheme (GFile *file);
Gets the URI scheme for a GFile. RFC 3986 decodes the scheme as:
URI = scheme ":" hier-part [ "?" query ] [ "#" fragment ]
Common schemes include "file", "http", "ftp", etc.
This call does no blocking i/o.
GFileInputStream* g_file_read (GFile *file, GCancellable *cancellable, GError **error);
Opens a file for reading. The result is a GFileInputStream that can be used to read the contents of the file.
If cancellable is not NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error G_IO_ERROR_CANCELLED will be returned.
If the file does not exist, the G_IO_ERROR_NOT_FOUND error will be returned. If the file is a directory, the G_IO_ERROR_IS_DIRECTORY error will be returned. Other errors are possible too, and depend on what kind of filesystem the file is on.
|

Returns : |
GFileInputStream or NULL on error.
|
void g_file_read_async (GFile *file, int io_priority, GCancellable *cancellable, GAsyncReadyCallback callback, gpointer user_data);
Asynchronously opens file for reading.
For more details, see g_file_read() which is
the synchronous version of this call.
When the operation is finished, callback will be called. You can then call
g_file_read_finish() to get the result of the operation.

|
a GError, or NULL
|
Returns : |
a GFileInputStream or NULL on error.
|
GFileOutputStream* g_file_append_to (GFile *file, GFileCreateFlags flags, GCancellable *cancellable, GError **error);
Gets an output stream for appending data to the file. If the file doesn't already exist it is created.
By default files created are generally readable by everyone,
but if you pass G_FILE_CREATE_PRIVATE in flags the file
will be made readable only to the current user, to the level that
is supported on the target filesystem.
If cancellable is not NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error G_IO_ERROR_CANCELLED will be returned.
Some file systems don't allow all file names, and may return an G_IO_ERROR_INVALID_FILENAME error. If the file is a directory the G_IO_ERROR_IS_DIRECTORY error will be returned. Other errors are possible too, and depend on what kind of filesystem the file is on.
|

GFileOutputStream* g_file_create (GFile *file, GFileCreateFlags flags, GCancellable *cancellable, GError **error);
Creates a new file and returns an output stream for writing to it. The file must not already exists.
By default files created are generally readable by everyone,
but if you pass G_FILE_CREATE_PRIVATE in flags the file
will be made readable only to the current user, to the level that
is supported on the target filesystem.
If cancellable is not NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error G_IO_ERROR_CANCELLED will be returned.
If a file with this name already exists the G_IO_ERROR_EXISTS error will be returned. If the file is a directory the G_IO_ERROR_IS_DIRECTORY error will be returned. Some file systems don't allow all file names, and may return an G_IO_ERROR_INVALID_FILENAME error, and if the name is to long G_IO_ERROR_FILENAME_TOO_LONG will be returned. Other errors are possible too, and depend on what kind of filesystem the file is on.
|
input GFile. |
|
a set of GFileCreateFlags. |
|
optional GCancellable object, NULL to ignore.
|
|
a GError, or NULL
|
Returns : |
a GFileOutputStream for the newly created file, or
NULL on error.
|
GFileOutputStream* g_file_replace (GFile *file, const char *etag, gboolean make_backup, GFileCreateFlags flags, GCancellable *cancellable, GError **error);
Returns an output stream for overwriting the file, possibly creating a backup copy of the file first.
This will try to replace the file in the safest way possible so that any errors during the writing will not affect an already existing copy of the file. For instance, for local files it may write to a temporary file and then atomically rename over the destination when the stream is closed.
By default files created are generally readable by everyone,
but if you pass G_FILE_CREATE_PRIVATE in flags the file
will be made readable only to the current user, to the level that
is supported on the target filesystem.
If cancellable is not NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error G_IO_ERROR_CANCELLED will be returned.
If you pass in a non-NULL etag value, then this value is
compared to the current entity tag of the file, and if they differ
an G_IO_ERROR_WRONG_ETAG error is returned. This generally means
that the file has been changed since you last read it. You can get
the new etag from g_file_output_stream_get_etag() after you've
finished writing and closed the GFileOutputStream. When you load
a new file you can use g_file_input_stream_query_info() to get
the etag of the file.
If make_backup is TRUE, this function will attempt to make a backup
of the current file before overwriting it. If this fails a G_IO_ERROR_CANT_CREATE_BACKUP
error will be returned. If you want to replace anyway, try again with
make_backup set to FALSE.
If the file is a directory the G_IO_ERROR_IS_DIRECTORY error will be returned, and if the file is some other form of non-regular file then a G_IO_ERROR_NOT_REGULAR_FILE error will be returned. Some file systems don't allow all file names, and may return an G_IO_ERROR_INVALID_FILENAME error, and if the name is to long G_IO_ERROR_FILENAME_TOO_LONG will be returned. Other errors are possible too, and depend on what kind of filesystem the file is on.

GFileInfo* g_file_query_info (GFile *file, const char *attributes, GFileQueryInfoFlags flags, GCancellable *cancellable, GError **error);
Gets the requested information about specified file. The result
is a GFileInfo object that contains key-value attributes (such as
the type or size of the file).
The attribute value is a string that specifies the file attributes that
should be gathered. It is not an error if it's not possible to read a particular
requested attribute from a file - it just won't be set. attribute should
be a comma-separated list of attribute or attribute wildcards. The wildcard "*"
means all attributes, and a wildcard like "standard::*" means all attributes in the standard
namespace. An example attribute query be "standard::*,owner::user".
The standard attributes are available as defines, like G_FILE_ATTRIBUTE_STANDARD_NAME.
If cancellable is not NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error G_IO_ERROR_CANCELLED will be returned.
For symlinks, normally the information about the target of the
symlink is returned, rather than information about the symlink itself.
However if you pass G_FILE_QUERY_INFO_NOFOLLOW_SYMLINKS in flags the
information about the symlink itself will be returned. Also, for symlinks
that point to non-existing files the information about the symlink itself
will be returned.
If the file does not exist, the G_IO_ERROR_NOT_FOUND error will be returned. Other errors are possible too, and depend on what kind of filesystem the file is on.

is a GFileInfo object that contains key-value attributes (such as type or size
for the file).
For more details, see g_file_query_info() which is

|
gboolean g_file_query_exists (GFile *file, GCancellable *cancellable);
Utility function to check if a particular file exists. This is
implemented using g_file_query_info() and as such does blocking I/O.
Note that in many cases it is racy to first check for file existance and then execute something based on the outcome of that, because the file might have been created or removed inbetween the operations. The general approach to handling that is to not check, but just do the operation and handle the errors as they come.
As an example of race-free checking, take the case of reading a file, and
if it doesn't exist, creating it. There are two racy versions: read it, and
on error create it; and: check if it exists, if not create it. These
can both result in two processes creating the file (with perhaps a partially
written file as the result). The correct approach is to always try to create
the file with g_file_create() which will either atomically create the file
or fail with a G_IO_ERROR_EXISTS error.
However, in many cases an existance check is useful in a user interface, for instance to make a menu item sensitive/insensitive, so that you don't have to fool users that something is possible and then just show and error dialog. If you do this, you should make sure to also handle the errors that can happen due to races when you execute the operation.
|
input GFile. |
|
optional GCancellable object, NULL to ignore.
|
Returns : |
TRUE if the file exists (and can be detected without error), FALSE otherwise (or if cancelled).
|
GFileInfo* g_file_query_filesystem_info (GFile *file, const char *attributes, GCancellable *cancellable, GError **error);
Similar to g_file_query_info(), but obtains information
about the filesystem the file is on, rather than the file itself.
For instance the amount of space available and the type of
the filesystem.
The attribute value is a string that specifies the file attributes that
should be gathered. It is not an error if it's not possible to read a particular
requested attribute from a file - it just won't be set. attribute should
be a comma-separated list of attribute or attribute wildcards. The wildcard "*"
means all attributes, and a wildcard like "fs:*" means all attributes in the fs
namespace. The standard namespace for filesystem attributes is "fs".
Common attributes of interest are G_FILE_ATTRIBUTE_FILESYSTEM_SIZE
(the total size of the filesystem in bytes), G_FILE_ATTRIBUTE_FILESYSTEM_FREE (number of
bytes available), and G_FILE_ATTRIBUTE_FILESYSTEM_TYPE (type of the filesystem).
If cancellable is not NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error G_IO_ERROR_CANCELLED will be returned.
If the file does not exist, the G_IO_ERROR_NOT_FOUND error will be returned. Other errors are possible too, and depend on what kind of filesystem the file is on.
GMount* g_file_find_enclosing_mount (GFile *file, GCancellable *cancellable, GError **error);
If the GFileIface for file does not have a mount (e.g. possibly a
remote share), error will be set to G_IO_ERROR_NOT_FOUND and NULL
will be returned.
If cancellable is not NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error G_IO_ERROR_CANCELLED will be returned.
void g_file_find_enclosing_mount_async (GFile *file, int io_priority, GCancellable *cancellable, GAsyncReadyCallback callback, gpointer user_data);
Asynchronously gets the mount for the file.
For more details, see g_file_find_enclosing_mount() which is
the synchronous version of this call.
When the operation is finished, callback will be called. You can then call
g_file_find_enclosing_mount_finish() to get the result of the operation.

GFileEnumerator* g_file_enumerate_children (GFile *file, const char *attributes, GFileQueryInfoFlags flags, GCancellable *cancellable, GError **error);
Gets the requested information about the files in a directory. The result is a GFileEnumerator object that will give out GFileInfo objects for all the files in the directory.
The attribute value is a string that specifies the file attributes that
should be gathered. It is not an error if it's not possible to read a particular
requested attribute from a file - it just won't be set. attribute should
be a comma-separated list of attribute or attribute wildcards. The wildcard "*"
means all attributes, and a wildcard like "standard::*" means all attributes in the standard
namespace. An example attribute query be "standard::*,owner::user".
The standard attributes are available as defines, like G_FILE_ATTRIBUTE_STANDARD_NAME.
If cancellable is not NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error G_IO_ERROR_CANCELLED will be returned.
If the file does not exist, the G_IO_ERROR_NOT_FOUND error will be returned. If the file is not a directory, the G_FILE_ERROR_NOTDIR error will be returned. Other errors are possible too.

GFile* g_file_set_display_name (GFile *file, const char *display_name, GCancellable *cancellable, GError **error);
Renames file to the specified display name.
The display name is converted from UTF8 to the correct encoding for the target
filesystem if possible and the file is renamed to this.
If you want to implement a rename operation in the user interface the edit name
(G_FILE_ATTRIBUTE_STANDARD_EDIT_NAME) should be used as the initial value in the rename
widget, and then the result after editing should be passed to g_file_set_display_name().
On success the resulting converted filename is returned.
If cancellable is not NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error G_IO_ERROR_CANCELLED will be returned.
void g_file_set_display_name_async (GFile *file, const char *display_name, int io_priority, GCancellable *cancellable, GAsyncReadyCallback callback, gpointer user_data);
Asynchronously sets the display name for a given GFile.
For more details, see g_set_display_name() which is
the synchronous version of this call.
When the operation is finished, callback will be called. You can then call
g_file_set_display_name_finish() to get the result of the operation.

GFile* g_file_set_display_name_finish (GFile *file, GAsyncResult *res, GError **error);
Finishes setting a display name started with
g_file_set_display_name_async().
gboolean g_file_delete (GFile *file, GCancellable *cancellable, GError **error);
Deletes a file.
If cancellable is not NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error G_IO_ERROR_CANCELLED will be returned.
gboolean g_file_trash (GFile *file, GCancellable *cancellable, GError **error);
Sends file to the "Trashcan", if possible. This is similar to
deleting it, but the user can recover it before emptying the trashcan.
Not all file systems support trashing, so this call can return the
G_IO_ERROR_NOT_SUPPORTED error.
If cancellable is not NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error G_IO_ERROR_CANCELLED will be returned.
gboolean g_file_copy (GFile *source, GFile *destination, GFileCopyFlags flags, GCancellable *cancellable, GFileProgressCallback progress_callback, gpointer progress_callback_data, GError **error);
Copies the file source to the location specified by destination.
Can not handle recursive copies of directories.
If the flag G_FILE_COPY_OVERWRITE is specified an already
existing destination file is overwritten.
If the flag G_FILE_COPY_NOFOLLOW_SYMLINKS is specified then symlinks
will be copied as symlinks, otherwise the target of the
source symlink will be copied.
If cancellable is not NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error G_IO_ERROR_CANCELLED will be returned.
If progress_callback is not NULL, then the operation can be monitored by
setting this to a GFileProgressCallback function. progress_callback_data
will be passed to this function. It is guaranteed that this callback will
be called after all data has been transferred with the total number of bytes
copied during the operation.
If the source file does not exist then the G_IO_ERROR_NOT_FOUND
error is returned, independent on the status of the destination.
If G_FILE_COPY_OVERWRITE is not specified and the target exists, then the error G_IO_ERROR_EXISTS is returned.
If trying to overwrite a file over a directory the G_IO_ERROR_IS_DIRECTORY error is returned. If trying to overwrite a directory with a directory the G_IO_ERROR_WOULD_MERGE error is returned.
If the source is a directory and the target does not exist, or G_FILE_COPY_OVERWRITE is specified and the target is a file, then the G_IO_ERROR_WOULD_RECURSE error is returned.
If you are interested in copying the GFile object itself (not the on-disk
file), see g_file_dup().

Copies the file source to the location specified by destination
asynchronously. For details of the behaviour, see g_file_copy().
If progress_callback is not NULL, then that function that will be called
just like in g_file_copy(), however the callback will run in the main loop,
not in the thread that is doing the I/O operation.
When the operation is finished, callback will be called. You can then call
g_file_copy_finish() to get the result of the operation.

g_file_copy_async().
gboolean g_file_move (GFile *source, GFile *destination, GFileCopyFlags flags, GCancellable *cancellable, GFileProgressCallback progress_callback, gpointer progress_callback_data, GError **error);
Tries to move the file or directory source to the location specified by destination.
If native move operations are supported then this is used, otherwise a copy + delete
fallback is used. The native implementation may support moving directories (for instance
on moves inside the same filesystem), but the fallback code does not.
If the flag G_FILE_COPY_OVERWRITE is specified an already
existing destination file is overwritten.
If the flag G_FILE_COPY_NOFOLLOW_SYMLINKS is specified then symlinks
will be copied as symlinks, otherwise the target of the
source symlink will be copied.
If cancellable is not NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error G_IO_ERROR_CANCELLED will be returned.
If progress_callback is not NULL, then the operation can be monitored by
setting this to a GFileProgressCallback function. progress_callback_data
will be passed to this function. It is guaranteed that this callback will
be called after all data has been transferred with the total number of bytes
copied during the operation.
If the source file does not exist then the G_IO_ERROR_NOT_FOUND
error is returned, independent on the status of the destination.
If G_FILE_COPY_OVERWRITE is not specified and the target exists, then the error G_IO_ERROR_EXISTS is returned.
If trying to overwrite a file over a directory the G_IO_ERROR_IS_DIRECTORY error is returned. If trying to overwrite a directory with a directory the G_IO_ERROR_WOULD_MERGE error is returned.
If the source is a directory and the target does not exist, or G_FILE_COPY_OVERWRITE is specified and the target is a file, then the G_IO_ERROR_WOULD_RECURSE error may be returned (if the native move operation isn't available).

If there is any error during this operation then error will be set to
the first error. Error on particular fields are flagged by setting
the "status" field in the attribute value to
G_FILE_ATTRIBUTE_STATUS_ERROR_SETTING, which means you can also detect
further errors.

user_user data, and the operation can be finalized with
g_file_replace_contents_finish().
If cancellable is not NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error G_IO_ERROR_CANCELLED will be returned.
If make_backup is TRUE, this function will attempt to
make a backup of file.
|
input GFile. |
|
string of contents to replace the file with. |
|
the length of contents in bytes.
|
|
a new entity tag for the file.
|
|
TRUE if a backup should be created.
|
|
a set of GFileCreateFlags. |
|
optional GCancellable object, NULL to ignore.
|
|
a GAsyncReadyCallback to call when the request is satisfied |
|
the data to pass to callback function |
gboolean g_file_replace_contents_finish (GFile *file, GAsyncResult *res, char **new_etag, GError **error);
Finishes an asynchronous replace of the given file. See
g_file_replace_contents_async(). Sets new_etag to the new entity
tag for the document, if present.
|
input GFile. |
|
a GAsyncResult. |
|
a location of a new entity tag
for the document. This should be freed with g_free() when it is no
longer needed.
|
|
a GError, or NULL
|
Returns : |
TRUE on success, FALSE on failure.
|
gboolean g_file_copy_attributes (GFile *source, GFile *destination, GFileCopyFlags flags, GCancellable *cancellable, GError **error);
Copies the file attributes from source to destination.
Normally only a subset of the file attributes are copied,
those that are copies in a normal file copy operation
(which for instance does not include e.g. mtime). However
if G_FILE_COPY_ALL_METADATA is specified in flags, then
all the metadata that is possible to copy is copied.
|
a GFile with attributes. |
|
a GFile to copy attributes to. |
|
a set of GFileCopyFlags. |
|
optional GCancellable object, NULL to ignore.
|
|
a GError, NULL to ignore.
|
Returns : |
TRUE if the attributes were copied successfully, FALSE otherwise.
