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
       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.

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

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);
