xt_ff_printf(3)

NAME
xt_ff_printf() - Print formatted data to a fast file stream

LIBRARY
#include <xtend/fast-file.h>
-lxtend

SYNOPSIS
int     xt_ff_printf(xt_ff_t *stream, const char *format, ...)

ARGUMENTS
stream  Pointer to an xt_ff_t object opened by xt_ff_open(3)
format  Format string indicating how remaining arguments are printed

DESCRIPTION
xt_ff_printf(3) writes formatted data to a xt_ff_t stream the same was as fprintf(3) writes to a FILE stream. The xt_ff_ile_t system is simpler than and much faster than traditional FILE on typical systems. It is intended for processing large files character-by-character, where low-level block I/O is not convenient, but FILE I/O causes a bottleneck.

RETURN VALUES
The number of characters written

EXAMPLES
xt_ff_ile_t *stream;
int     count = 1;
if ( (stream = xt_ff_open(filename, O_WRONLY|O_CREAT|O_TRUNC)) == NULL )
{
    fprintf(stderr, "Could not open %s.n", filename);
    exit(EX_CANTCREAT);
}
xt_ff_printf(stream, "%dn", count);
xt_ff_close(stream);
