sysevent_post_event(3SYSEVENT)				  System Event Library Functions			    sysevent_post_event(3SYSEVENT)

NAME

       sysevent_post_event - post system event for applications

SYNOPSIS

       cc  [ flag... ]	file... -lsysevent  -lnvpair  [ library... ]
       #include <libsysevent.h>
       #include <libnvpair.h>

       int sysevent_post_event(char *class, char *subclass, char *vendor,
	    char *publisher, nvlist_t *attr_list, sysevent_id_t *eid);

PARAMETERS

       attr_list    pointer  to  an nvlist_t, listing the name-value attributes associated with the event, or NULL if there are no such attributes
		    for this event

       class	    pointer to a string defining the event class

       eid	    pointer to a system unique identifier

       publisher    pointer to a string defining the event's publisher nam

       subclass     pointer to a string defining the event subclass

       vendor	    pointer to a string defining the vendor

DESCRIPTION

       The sysevent_post_event() function causes a system event of the specified class, subclass, vendor, and publisher to be generated on  behalf
       of the caller and queued for delivery to  the sysevent daemon syseventd(1M).

       The  vendor should be the company stock symbol (or similarly enduring identifier) of the event posting application. The publisher should be
       the name of the application generating the event.

       For example, all events posted by Sun applications begin with the company's stock symbol, "SUNW". The publisher is usually the name of  the
       application generating the system event. A system event generated by devfsadm(1M) has a publisher string of devfsadm.

       The publisher information is used by sysevent consumers to filter unwanted event publishers.

       Upon successful queuing of the system event, a unique identifier is assigned to eid.

RETURN VALUES

       The  sysevent_post_event()  function  returns  0 if the system event has been queued successfully for delivery. Otherwise it returns -1 and
       sets errno to indicate the error.

ERRORS

       The sysevent_post_event() function will fail if:

       ENOMEM	 Insufficient resources to queue the system event.

       EIO	 The syseventd daemon is not responding and events cannot be queued or delivered at this time.

       EINVAL	 Invalid argument.

       EPERM	 Permission denied.

       EFAULT	 A copy error occurred.

EXAMPLES

       Example 1 Post a system event event with no attributes.

       The following example posts a system event event with no attributes.

	 if (sysevent_post_event(EC_PRIV, "ESC_MYSUBCLASS", "SUNW", argv[0],
	     NULL), &eid == -1) {
		 fprintf(stderr, "error logging system event
");
	 }

       Example 2 Post a system event with two name-value pair attributes.

       The following example posts a system event event with two name-value pair attributes, an integer value and a string.

	 nvlist_t	 *attr_list;
	 uint32_t	 uint32_val = 0XFFFFFFFF;
	 char		 *string_val = "string value data";

	 if (nvlist_alloc(&attr_list, 0, 0) == 0) {
		 err = nvlist_add_uint32(attr_list, "uint32 data", uint32_val);
		 if (err == 0)
			 err = nvlist_add_string(attr_list, "str data",
			     string_val);
		 if (err == 0)
			 err = sysevent_post_event(EC_PRIV, "ESC_MYSUBCLASS",
			     "SUNW", argv[0], attr_list, &eid);
		 if (err != 0)
			 fprintf(stderr, "error logging system event
");
		 nvlist_free(attr_list);
	 }
