SYNOPSIS

#include <libexplain/readdir.h>

struct dirent *explain_readdir_or_die(DIR *dir);

DESCRIPTION

The explain_readdir_or_die function is used to call the readdir(2) system call. On failure an explanation will be printed to stderr, obtained from explain_readdir(3), and then the process terminates by calling exit(EXIT_FAILURE).

This function is intended to be used in a fashion similar to the following example:

explain_readdir_or_die(dir);

dir

The dir, exactly as to be passed to the readdir(2) system call.

Returns:

a pointer to a dirent structure, or NULL if end-of-file is reached. On failure, prints an explanation and exits.
