The explain_mknod_or_die function is used to call the
mknod(2) system call. On failure an explanation will be printed to
stderr, obtained from the explain_mknod(3) function, and
then the process terminates by calling exit(EXIT_FAILURE).
The explain_mknod_on_error function is used to call the
mknod(2) system call. On failure an explanation will be printed to
stderr, obtained from the explain_mknod(3) function, but
still returns to the caller.
pathname
The pathname, exactly as to be passed to the mknod(2) system call.
mode
The mode, exactly as to be passed to the mknod(2) system call.
dev
The dev, exactly as to be passed to the mknod(2) system call.
RETURN VALUE
The explain_mknod_or_die function only returns on success, see
mknod(2) for more information. On failure, prints an explanation
and exits, it does not return.
The explain_mknod_on_error function always returns the value return
by the wrapped mknod(2) system call.
EXAMPLE
The explain_mknod_or_die function is intended to be used in a
fashion similar to the following example:
