The MonitorFromPoint function retrieves a handle to the display monitor that contains a specified point.


HMONITOR MonitorFromPoint(
  _In_  POINT pt,
  _In_  DWORD dwFlags
);

pt [in]

A POINT structure that specifies the point of interest in virtual-screen coordinates.

dwFlags [in]

Determines the function's return value if the point is not contained within any display monitor.

This parameter can be one of the following values.

Value	Meaning
MONITOR_DEFAULTTONEAREST	Returns a handle to the display monitor that is nearest to the point.
MONITOR_DEFAULTTONULL	Returns NULL.
MONITOR_DEFAULTTOPRIMARY	Returns a handle to the primary display monitor.

If the point is contained by a display monitor, the return value is an HMONITOR handle to that display monitor.

If the point is not contained by a display monitor, the return value depends on the value of dwFlags.
