 * File Description:
 *   Memory-resident FIFO storage area (to be used e.g. in I/O buffering)
 *
 *   This is just a back-compatibility interface("Nlm_*") to the real
 *   BUF API located in "ncbi_buffer.[ch]".
 *   Unlike the "real" BUF API, this API uses:
 *    a) "Nlm_" name prefix for structures, types and functions;
 *    b) "Nlm_*" fixed size integer types like "Nlm_Uint4";
 *    c) "Nlm_Boolean" rather than a native "int" for the boolean type;
 *    d) [MSWIN] "NLM_EXTERN" rather than just "extern" to ease the compilation
 *       for MSWIN DLL.

 * $Log: ncbibuf.c,v $
 * Revision 6.7  2000/02/25 16:45:54  vakatov
 * Redesigned to really share "ncbi_*.[ch]" etc. between the C and
 * the C++ toolkits, and even to use them in a "standalone" fashion
 *
 * Revision 6.6  1999/10/12 16:40:26  vakatov
 * Deleted all test code as there is one in "test/test_ncbi_buffer.c" now
 *
 * Revision 6.5  1999/08/17 22:30:21  vakatov
 * Use "Nlm_BUF" to avoid name clash with "BUF" in "ncbi_buffer.h" when
 * compiling with MipsPro IRIX compiler
 *
 * Revision 6.4  1999/08/17 19:47:24  vakatov
 * Moved all real code from NCBIBUF to NCBI_BUFFER;  the code has been cleaned
 * from the NCBI C toolkit specific types and API calls.
 * NCBIBUF module still exists for the backward compatibility -- it
 * provides old NCBI-wise interface.
