pActionQueue

Get items from the Message Queue. Initialize the Message Queue.

Syntax

pActionQueue ( in vlOperation,
inout vlAction,
inout vlWindowName )

Parameters

vlOperation	A string with the value “GET”, “PEEK”, or “INIT”.
vlAction	The action returned for either the “GET” or “PEEK” operations.
vlWindowName	The window name returned for either the “GET” or “PEEK” operations.

Comments

The pActionQueue function is a front end to pMessageQueue providing an easier to use interface to the “GET”, “PEEK”, and “INIT” operations. The “GET” operation gets the next action from the Message Queue and returns the action and the window for which the action is intended. The “PEEK” operation is similar to “GET” but it leaves the action on the queue. The “INIT” operation initializes the Message Queue.
