DESCRIPTION

13       The explain_opendir_or_die function is used to call the opendir(3) sys‐
14       tem call.  On  failure  an  explanation  will  be  printed  to  stderr,
15       obtained  from  explain_opendir(3),  and then the process terminates by
16       calling exit(EXIT_FAILURE).
17
18       This function is intended to be used in a fashion similar to  the  fol‐
19       lowing example:
20              DIR *dir = explain_opendir_or_die(pathname);
21
22       pathname
23               The  pathname, exactly as to be passed to the opendir(3) system
24               call.
25
26       Returns:
27               On success, a pointer to the  directory  stream.   On  failure,
28               prints an explanation and exits, does not return.
