Creates an Apple event with several important attributes but no parameters.
- macOS 10.0+
- Core Services
A pointer to an address descriptor. Before calling
AECreate, you set the descriptor to identify the target (or server) application for the Apple event. This parameter becomes accessible through the
keyattribute of the Apple event. See
The return ID for the created Apple event. If you pass a value of
k, the Apple Event Manager assigns the created Apple event a return ID that is unique to the current session. If you pass any other value, the Apple Event Manager assigns that value for the ID. This parameter becomes accessible through the
Auto Generate Return ID
keyattribute of the Apple event. The return ID constant is described in ID Constants for the AECreateAppleEvent Function. See
The transaction ID for this Apple event. A transaction is a sequence of Apple events that are sent back and forth between the client and server applications, beginning with the client’s initial request for a service. All Apple events that are part of a transaction must have the same transaction ID. You can specify the
kconstant if the Apple event is not one of a series of interdependent Apple events. This parameter becomes accessible through the
Any Transaction ID
keyattribute of the Apple event. This transaction ID constant is described in ID Constants for the AECreateAppleEvent Function. See
A pointer to an Apple event. On successful return, the new Apple event. On error, a null descriptor (one with descriptor type
type). If the function returns successfully, your application should call the
AEDisposefunction to dispose of the resulting Apple event after it has finished using it. See the
A result code. See Result Codes.
AECreatefunction creates an empty Apple event. You can add parameters to the Apple event after you create it with the functions described in Apple Event Manager.
