EnumWindowStations

The EnumWindowStations function enumerates all window stations in the system by passing the name of each window station, in turn, to an application-defined callback function.

BOOL EnumWindowStations(
  WINSTAENUMPROC lpEnumFunc, // pointer to the callback function
  LPARAM lParam              // value to pass to the callback function
);
 

Parameters

lpEnumFunc

Pointer to an application-defined EnumWindowStationProc callback function.

lParam

Specifies a 32-bit application-defined value to be passed to the callback function.

Return Values

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

Remarks

The EnumWindowStations function enumerates only those window stations for which the calling process has WINSTA_ENUMERATE access.

EnumWindowStations repeatedly invokes the lpEnumFunc callback function until the last window station is enumerated or the callback function returns FALSE.
