           Since glibc 2.10:
               _XOPEN_SOURCE >= 700 || _POSIX_C_SOURCE >= 200809L

DESCRIPTION
       The functions dprintf() and vdprintf() (as found in the glibc2 library)
       are exact analogs of fprintf(3) and vfprintf(3), except that they  out-
       put 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.
