1/6/2010

This structure contains parameter values specifying a change in status of the line the application currently has open. The lineGetMessage function returns the LINEMESSAGE structure.

Syntax

typedef struct linemessage_tag {
  DWORD hDevice;
  DWORD dwMessageID;
  DWORD_PTR dwCallbackInstance;
  DWORD_PTR dwParam1;
  DWORD_PTR dwParam2;
  DWORD_PTR dwParam3;
} LINEMESSAGE, FAR* LPLINEMESSAGE;

Members

  • hDevice
    Handle to either a line device or a call. The nature of this handle (line handle or call handle) can be determined by the context provided by dwMessageID.
  • dwMessageID
    Line or call device message.
  • dwCallbackInstance
    Instance data passed back to the application, which was specified by the application in the dwCallBackInstance parameter of the lineInitializeEx function. This DWORD is not interpreted by TAPI.
  • dwParam1
    Parameter for the message.
  • dwParam2
    Parameter for the message.
