Linux 2.6 - man page for vdprintf (linux section 3)

DPRINTF(3)			    Linux Programmer's Manual			       DPRINTF(3)

NAME
       dprintf, vdprintf - print to a file descriptor

SYNOPSIS
       #include <stdio.h>

       int dprintf(int fd, const char *format, ...);

       int vdprintf(int fd, const char *format, va_list ap);

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       dprintf(), vdprintf():
	   Since glibc 2.10:
	       _XOPEN_SOURCE >= 700 || _POSIX_C_SOURCE >= 200809L
	   Before glibc 2.10:
	       _GNU_SOURCE

DESCRIPTION
       The  functions dprintf() and vdprintf() (as found in the glibc2 library) are exact analogs
       of fprintf(3) and vfprintf(3), except that they output to a file descriptor fd instead  of
       to a stdio stream.

CONFORMING TO
       These functions are GNU extensions that are nowadays specified in POSIX.1-2008.
