lineProxyMessage  43IXN55 

The lineProxyMessage function is used by a registered proxy request handler to generate TAPI messages related to its role. For example, an ACD agent handler can use this function to generate LINE_AGENTSTATUS3O9O05F messages that will be received by all applications that have the specified line open. TAPI suppresses generation of the message on the hLine specified in the function parameters.

    DWORD dwParam3

 

   );

 

 

Parameters

hLine

A handle to the open line device. This will be converted by TAPI into the correct hLine for each application that receives the message.

hCall

If the message is related to a specific call (which it is not, in the case of LINE_AGENTSTATUS), specifies the proxy handler's handle to that call; shall be set to NULL for messages not related to a specific call. This will be converted by TAPI into the correct hCall for each application that receives the message.

dwMsg

The TAPI message to be generated. This must be a message that is permitted to be generated by proxy handlers.

dwParam1

dwParam2

dwParam3

The parameters associated with the message to be sent.
