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);
