NAME
       explain_gethostbyname_or_die - get host address by host name and	report
       errors

SYNOPSIS
       #include	<libexplain/gethostbyname.h>
       struct hostent *explain_gethostbyname_or_die(const char *name);
       struct hostent *explain_gethostbyname_on_error(const char *name);

DESCRIPTION
       The explain_gethostbyname_or_die	function is used to call the  gethost-
       byname(3)  system  call.	 On  failure an	explanation will be printed to
       stderr, obtained	from the explain_gethostbyname(3) function,  and  then
       the process terminates by calling exit(EXIT_FAILURE).

       The  explain_gethostbyname_on_error  function is	used to	call the geth-
       ostbyname(3) system call. On failure an explanation will	be printed  to
       stderr,	obtained from the explain_gethostbyname(3) function, but still
       returns to the caller.

       name    The name, exactly as to be passed to the	gethostbyname(3)  sys-
	       tem call.

RETURN VALUE
       The  explain_gethostbyname_or_die function only returns on success, see
       gethostbyname(3)	for more information. On failure, prints  an  explana-
       tion and	exits, it does not return.

       The  explain_gethostbyname_on_error  function  always returns the value
       return by the wrapped gethostbyname(3) system call.

EXAMPLE
       The explain_gethostbyname_or_die	function is intended to	be used	 in  a
       fashion similar to the following	example:
	      struct hostent *result = explain_gethostbyname_or_die(name);
