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);
