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
