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.
