explain_setdomainname_or_diLibrary Functions Maexplain_setdomainname_or_die(3)

NAME
       explain_setdomainname_or_die - set domain name and report errors

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	setdo-
       mainname(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	setdo-
       mainname(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.

       data    The  data, exactly as to	be passed to the setdomainname(2) sys-
	       tem call.

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

RETURN VALUE
       The  explain_setdomainname_or_die function only returns on success, see
       setdomainname(2)	for more information. On failure, prints  an  explana-
       tion and	exits, it does not return.

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

EXAMPLE
       The explain_setdomainname_or_die	function is intended to	be used	 in  a
       fashion similar to the following	example:
	      explain_setdomainname_or_die(data, data_size);
