NAME         top

       dprintf, vdprintf - print to a file descriptor

SYNOPSIS         top

   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         top

       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         top

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