NAME

buffer_flush - feed buffer to write function

SYNTAX

#include <libowfat/buffer.h>

int buffer_flush (buffer* b );

DESCRIPTION

buffer_flush feeds a string d [0], d [1], ..., d [ dlen -1] to the write operation by calling

op ( fd , d , dlen )

If op successfully handles one or more bytes at the beginning of the string, it must return the number of bytes handled; if this number is smaller than dlen , buffer_flush will call op again with the rest of the string. If op does not handle any bytes, and does not encounter an error, it must return 0, or return -1 with errno set to EINTR; in either case, buffer_flush will immediately call op again. If op encounters an error, it must return -1 with errno set to something other than EINTR; buffer_flush will pass the error to the caller.

On success, buffer_flush returns 0. On error, buffer_flush returns -1, setting errno appropriately.
