NAME

       buffer.h - generic read/write buffering

SYNTAX

       #include <buffer.h>

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

DESCRIPTION

       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.

EXAMPLE

       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_putulong(buffer_2,got);
         buffer_puts(buffer_2," bytes, but expected at least ");
         buffer_putulong(buffer_2,expected);
         buffer_putsflush(buffer_2," bytes!");
