IsMouseInPointerEnabled function (winuser.h)
Indicates whether EnableMouseInPointer is set for the mouse to act as a pointer input device and send WM_POINTER messages.
Syntax
BOOL IsMouseInPointerEnabled();
Return value
If EnableMouseInPointer is set, the return value is nonzero.
If EnableMouseInPointer is not set, the return value is zero.
Remarks
EnableMouseInPointer can be called only once in the context of a process lifetime. Prior to the first call, Windows Store apps run with mouse-in-pointer enabled, as do any desktop applications that consume mshtml.dll. All other desktop applications run with mouse-in-pointer disabled.
On the first call to EnableMouseInPointer in the process lifetime, the state is changed as specified and the call succeeds.
On subsequent calls to EnableMouseInPointer, the state will not change. If the current state is not equal to the specified state, the call fails.
Call IsMouseInPointerEnabled to verify the mouse-in-pointer state.
