Retrieves the physical monitors associated with an HMONITOR monitor handle.
Code examples:
How to adjust monitor brightness (Vista, monitor with DDC support)
Declaration:
BOOL GetPhysicalMonitorsFromHMONITOR(
  HMONITOR  hMonitor,
  DWORD  dwPhysicalMonitorArraySize,
  LPPHYSICAL_MONITOR  pPhysicalMonitorArray
);
FoxPro declaration:
DECLARE INTEGER GetPhysicalMonitorsFromHMONITOR IN dxva2;
    INTEGER hMonitor,;
    LONG dwPhysicalMonitorArraySize,;
    STRING @pPhysicalMonitorArray
Parameters:
hMonitor
[in] A monitor handle. Monitor handles are returned by several Multiple Display Monitor functions, including EnumDisplayMonitors and MonitorFromWindow.

dwPhysicalMonitorArraySize
[in] Number of elements in pPhysicalMonitorArray. To get the required size of the array, call GetNumberOfPhysicalMonitorsFromHMONITOR.

pPhysicalMonitorArray
[out] Pointer to an array of PHYSICAL_MONITOR structures. The caller must allocate the array.
Return value:
If the function succeeds, the return value is nonzero.
Usage:
cPhysMonitorArray=REPLICATE(CHR(0),1024)

= GetPhysicalMonitorsFromHMONITOR(hMonitor,;
    nPhysMonitorCount, @cPhysMonitorArray)

My comment:
When you are done using the monitor handles, close them by passing the pPhysicalMonitorArray array to the DestroyPhysicalMonitors function.
