lineGetQueueInfo

The lineGetQueueInfo function returns a structure holding the ACD information associated with a particular queue. It generates a LINE_PROXYREQUEST message to be sent to a registered proxy function handler, referencing a LINEPROXYREQUEST structure of type LINEPROXYREQUEST_GETQUEUEINFO.

LONG lineGetQueueInfo(        
  HLINE hLine,                
  DWORD dwQueueID,            
  LPLINEQUEUEINFO lpLineQueueInfo 
);

Parameters

hLine

A handle to the line device.

dwQueueID

The identifier of the queue whose information is to be retrieved.

lpLineQueueInfo

A pointer to a structure of type LINEQUEUEINFO. Upon successful completion of the request, this structure is filled with the queue statistics.
