EnumWindowStations單詞簡介
lpEnumFunc
A pointer to an application-defined EnumWindowStationProc callback function.
lParam
An application-defined value to be passed to the callback function.
EnumWindowStationsReturn Value
If the function succeeds, it returns the nonzero value returned by the callback function that was pointed to by lpEnumFunc.
If the function is unable to perform the enumeration, the return value is zero. Call GetLastError to get extended error information.
If the callback function fails, the return value is zero. The callback function can call SetLastError to set an error code for the caller to retrieve by calling GetLastError
EnumWindowStationsRemarks
The EnumWindowStations function enumerates only those window stations for which the calling process has the WINSTA_ENUMERATE access right. For more information, see Window Station Security and Access Rights.
EnumWindowStations repeatedly invokes the lpEnumFunc callback function until the last window station is enumerated or the callback function returns FALSE.
