{

ast_event_new()

struct ast_event* ast_event_new	(	enum ast_event_type	event_type,
			...
	)

Create a new event.

Parameters

event_type

The type of event to create

The rest of the arguments to this function specify information elements to add to the event. They are specified in the form:

<enum ast_event_ie_type>, [enum ast_event_ie_pltype, [payload] ]

and must end with AST_EVENT_IE_END.

If the ie_type specified is not AST_EVENT_IE_END, then it must be followed by a valid IE payload type. A payload must also be specified after the IE payload type.

Note

The EID IE will be appended automatically when this function is used with at least one IE specified.

Returns

This returns the event that has been created. If there is an error creating the event, NULL will be returned.

Example usage:

if (!(event = ast_event_new(AST_EVENT_MWI,
    AST_EVENT_IE_MAILBOX, AST_EVENT_IE_PLTYPE_STR, mailbox,
    AST_EVENT_IE_NEWMSGS, AST_EVENT_IE_PLTYPE_UINT, new,
    AST_EVENT_IE_OLDMSGS, AST_EVENT_IE_PLTYPE_UINT, old,
    AST_EVENT_IE_END))) {
      return;
}

This creates a MWI event with 3 information elements, a mailbox which is a string, and the number of new and old messages, specified as integers.
