11 void explain_mknod_or_die(const char *pathname, mode_t mode, dev_t

14 dev);

17 The explain_mknod_or_die function is used to call the mknod(2) system
18 call. On failure an explanation will be printed to stderr, obtained
19 from the explain_mknod(3) function, and then the process terminates by
20 calling exit(EXIT_FAILURE).
21
22 The explain_mknod_on_error function is used to call the mknod(2) system
23 call. On failure an explanation will be printed to stderr, obtained
24 from the explain_mknod(3) function, but still returns to the caller.

28 call.

40 the wrapped mknod(2) system call.

43 The explain_mknod_or_die function is intended to be used in a fashion
44 similar to the following example:
45 explain_mknod_or_die(pathname, mode, dev);
