NAME
     sysevent_get_vendor_name,             sysevent_get_pub_name,
     sysevent_get_pid  -  get vendor name, publisher name or pro-
     cessor ID of event

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

     char *sysevent_get_vendor_name(sysevent_t *ev);


     char *sysevent_get_pub_name(sysevent_t *ev);


     pid_t sysevent_get_pid(sysevent_t *ev);


PARAMETERS
     ev    handle to a system event object


DESCRIPTION
     The sysevent_get_pub_name() function returns  the  publisher
     name  for the sysevent handle, ev.  The publisher name iden-
     tifies the name of the publishing application or kernel sub-
     system of the sysevent.


     The sysevent_get_pid() function returns the process  ID  for
     the publishing application or SE_KERN_PID for sysevents ori-
     ginating in the kernel.  The publisher name and PID are use-
     ful for implementing event acknowledgement.


     The sysevent_get_vendor_name() function returns  the  vendor
     string  for  the publishing application or kernel subsystem.
     A vendor string is the company's stock symbol that  provided
     the  application or kernel subsystem that generated the sys-
     tem  event.   This  information  is  useful  for   filtering
     sysevents for one or more vendors.


     The interface manages the allocation of the vendor and  pub-
     lisher  name  strings, but it is the caller's responsibility
     to free the strings when they are no longer needed  by  cal-
     ling  free(3MALLOC).  If  the  new vendor and publisher name
     strings cannot be  created,  sysevent_get_vendor_name()  and
     sysevent_get_pub_name()  return  a  null pointer and may set
     errno to ENOMEM to indicate that the storage space available
     is insufficient.

EXAMPLES
     Example 1 Parse sysevent header information.


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


       char *vendor;
       char *pub;

       void
       event_handler(sysevent_t *ev)
       {
               if (strcmp(EC_PRIV, sysevent_get_class_name(ev)) != 0) {
                       return;
               }

               vendor = sysevent_get_vendor_name(ev);
               if (strcmp("SUNW", vendor) != 0) {
                       free(vendor);
                       return;
               }
               pub = sysevent_get_pub_name(ev);
               if (strcmp("test_daemon", pub) != 0) {
                       free(vendor);
                       free(pub);
                       return;
               }
               (void) kill(sysevent_get_pid(ev), SIGUSR1);
               free(vendor);
               free(pub);
       }
