SYNOPSIS
#include <libexplain/setdomainname.h> void explain_setdomainname_or_die(const char *data, size_t data_size); int explain_setdomainname_on_error(const char *data, size_t data_size);
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_setdomainname(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_setdomainname(3) function, but still
returns to the caller.

- tem call.
- data_size
- The data_size, exactly as to be passed to the setdomainname(2) system call.
RETURN VALUE

setdomainname(2) for more information. On failure, prints an explanation and exits, it does not return.
The explain_setdomainname_on_error function always returns the value return by the wrapped setdomainname(2) system call.
