generic read/write buffering


#include <buffer.h>

 buffer* buffer_0;   /* like stdio's stdin */
 buffer* buffer_1;   /* like stdio's stdout */
 buffer* buffer_2;   /* like stdio's stderr */


buffer.h provides a generic buffer interface that can be used for read and write buffering.  Buffers must be initialized with buffer_init.

A buffer can only be used for reading or writing at the same time, not both.

Unlike stdio, these write buffers are not flushed automatically at program termination; you must manually call buffer_flush, buffer_putsflush, buffer_putflush or buffer_putnlflush.


See buffer_init(3) for example read buffer code.  Here is typical code for printing an error message on stderr:

 #include <buffer.h>

 buffer_puts(buffer_2,"error: got only ");
 buffer_puts(buffer_2," bytes, but expected at least ");
 buffer_putsflush(buffer_2," bytes!");
