Get items from the Message Queue. Initialize the Message Queue.
pActionQueue ( in vlOperation,
inout vlWindowName )
|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.|
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.
