explain_opendir_or_die - open a directory and report errors
Synopsis
#include <libexplain/opendir.h>
DIR *explain_opendir_or_die(const char *pathname);
Description
The explain_opendir_or_die function is used to call the opendir(3) system call. On failure an explanation will be printed to stderr, obtained from explain_opendir(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:
-
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.
