krb5_pre_send_fn
¶
Hook function for inspecting or modifying messages sent to KDCs.
If the hook function sets reply_out , message will not be sent to the KDC, and the given reply will used instead.
If the hook function sets new_message_out , the given message will be sent to the KDC in place of message .
If the hook function returns successfully without setting either output, message will be sent to the KDC normally.
The hook function should use krb5_copy_data()
to construct the value for new_message_out or reply_out , to ensure that it can be freed correctly by the library.
