SYNOPSIS

#include <libexplain/opendir.h>

DIR *explain_opendir_or_die(const char *pathname);

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

DIR *dir = explain_opendir_or_die(pathname);
pathname
The pathname, exactly as to be passed to the opendir(3) system call.
Returns:
On success, a pointer to the directory stream. On failure, prints an explanation and exits, does not return.
