/*-
* AE Mach API --
*
* AppleEvents on OS X are implemented in terms of mach messages.
* To facilitate writing server processes that can send and receive
* AppleEvents, the following APIs are provided.
*
* AppleEvents are directed to a well known port uniquely tied to a
* process. The AE framework will discover this port based on the
* keyAddressAttr of the event (as specifed in AECreateAppleEvent by
* the target parameter.) If a port cannot be found,
* procNotFound (-600) will be returned on AESend.
*
* Of note is a new attribute for an AppleEvent, keyReplyPortAttr.
* This specifies the mach_port_t to which an AppleEvent reply
* should be directed. By default, replies are sent to the
* processes registered port where they are culled from the normal
* event stream if there is an outstanding AESend + kAEWaitReply.
* But it may be desirable for a client to specify their own port to
* receive quued replies.
* (In the case of AESendMessage with kAEWaitReply specified, an
* anonymous port will be used to block until the reply is received.)
*
* Not supplied is a convenience routine to block a server and
* process AppleEvents. This implementation will be detailed in a
* tech note.

* only if, you are not also using routines from HIToolbox. In that
* case, HIToolbox retains control of this port and AppleEvents are
