buffer

buffer(3)						     Library Functions Manual							 buffer(3)

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, buf-
       fer_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!");
