SYNOPSIS

       #include <libexplain/fdopendir.h>

DESCRIPTION

       The  explain_fdopendir_or_die  function  is  used  to  call  the  fdopendir(3) system call. On failure an
       explanation will be printed to stderr, obtained from the  explain_fdopendir(3)  function,  and  then  the
       process terminates by calling exit(EXIT_FAILURE).

       The  explain_fdopendir_on_error  function  is  used  to  call the fdopendir(3) system call. On failure an
       explanation will be printed to stderr, obtained from the explain_fdopendir(3) function, but still returns
       to the caller.

       fildes  The fildes, exactly as to be passed to the fdopendir(3) system call.

RETURN VALUE

       The explain_fdopendir_or_die function only returns on success, see fdopendir(3) for more information.  On

       system call.
