DESCRIPTION The explain_setdomainname_or_die function is used to call the setdomainname(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_set‐ domainname(3) function, and then the process terminates by calling exit(EXIT_FAILURE). The explain_setdomainname_on_error function is used to call the setdomainname(2) system call. On failure an explanation will be printed to stderr, obtained from the explain_set‐ domainname(3) function, but still returns to the caller. data The data, exactly as to be passed to the setdomainname(2) system call. data_size The data_size, exactly as to be passed to the setdomainname(2) system call.

The explain_setdomainname_on_error function always returns the value return by the wrapped setdomainname(2) system call.
