                               sysevent_get_class_name(3SYSEVENT)



NAME
     sysevent_get_class_name,         sysevent_get_subclass_name,
     sysevent_get_size, sysevent_get_seq, sysevent_get_time - get
     class name, subclass name, ID or buffer size of event

SYNOPSIS
     cc [flag...]  file... -lsysevent [library...]
     #include 

     char *sysevent_get_class_name(sysevent_t *ev);


     char *sysevent_get_subclass_name(sysevent_t *ev);


     int sysevent_get_size(sysevent_t *ev);


     uint64_t sysevent_get_seq(sysevent_t *ev);


     void sysevent_get_time(sysevent_t *ev, hrtime_t *etimep);


PARAMETERS
     ev        handle to event


     etimep    pointer to high resolution event time variable


DESCRIPTION
     The              sysevent_get_class_name()               and
     sysevent_get_subclass_name() functions return, respectively,
     the class and subclass names for the provided event ev.


     The sysevent_get_size() function returns  the  size  of  the
     event buffer, ev.


     The  sysevent_get_seq()  function  returns  a  unique  event
     sequence number of event ev. The sequence number is reset on
     every system boot.


     The sysevent_get_time() function writes the time  the  event
     was  published  into  the variable pointed to by etimep. The
     event time is added to the event just before it is put  into
     the kernel internal event queue.

EXAMPLES
     Example 1 Parse sysevent header information.


     The following example  parses  sysevent  header  information
     from an application's event handler.

                queue_event(new_ev);
       }
