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
       explanation 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

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