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.
