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);
