The explain_mkdir_or_die function
is used to call the mkdir(2) system
call. On failure an explanation will be
printed to stderr,
obtained from explain_mkdir(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_mkdir_or_die(pathname);
pathname
The pathname, exactly as to be passed to the mkdir(2) system call.
Returns:
This function only returns on success.
On failure, prints an explanation and exits.
