NAME

       explain_fdopendir_or_die - open a directory and report errors

SYNOPSIS

       #include <libexplain/fdopendir.h>
       DIR *explain_fdopendir_or_die(int fildes);
       DIR *explain_fdopendir_on_error(int fildes);

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 failure, prints an explanation and exits, it does not return.

       The explain_fdopendir_on_error function always returns the value  return  by  the  wrapped
       fdopendir(3) system call.

EXAMPLE

       The  explain_fdopendir_or_die  function is intended to be used in a fashion similar to the
       following example:
              DIR *result = explain_fdopendir_or_die(fildes);
