NAME
       explain_getdomainname_or_die - get domain name and report errors

SYNOPSIS
       #include <libexplain/getdomainname.h>
       void explain_getdomainname_or_die(char *data, size_t data_size);
       int explain_getdomainname_on_error(char *data, size_t data_size);

DESCRIPTION
       The  explain_getdomainname_or_die  function  is used to call the getdomainname(2) system call. On failure an explanation will be printed to
       stderr, obtained from the explain_getdomainname(3) function, and then the process terminates by calling exit(EXIT_FAILURE).

       The explain_getdomainname_on_error function is used to call the getdomainname(2) system call. On failure an explanation will be printed	to
       stderr, obtained from the explain_getdomainname(3) function, but still returns to the caller.

       data    The data, exactly as to be passed to the getdomainname(2) system call.

       data_size
	       The data_size, exactly as to be passed to the getdomainname(2) system call.

RETURN VALUE
       The  explain_getdomainname_or_die function only returns on success, see getdomainname(2) for more information. On failure, prints an expla-
       nation and exits, it does not return.

       The explain_getdomainname_on_error function always returns the value return by the wrapped getdomainname(2) system call.

EXAMPLE
