HWINSTA OpenWindowStationA( [in] LPCSTR lpszWinSta, [in] BOOL fInherit, [in] ACCESS_MASK dwDesiredAccess );
The name of the window station to be opened. Window station names are case-insensitive.
This window station must belong to the current session.
If this value is TRUE, processes created by this process will inherit the handle. Otherwise, the processes do not inherit this handle.
The access to the window station. For a list of access rights, see Window Station Security and Access Rights.
If the function succeeds, the return value is the handle to the specified window station.
If the function fails, the return value is NULL. To get extended error information, call GetLastError.
After you are done with the handle, you must call CloseWindowStation to free the handle.
The winuser.h header defines OpenWindowStation as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
