WTSOpenServerA function (wtsapi32.h)

Opens a handle to the specified Remote Desktop Session Host (RD Session Host) server.


  [in] LPSTR pServerName


[in] pServerName

Pointer to a null-terminated string specifying the NetBIOS name of the RD Session Host server.

Return value

If the function succeeds, the return value is a handle to the specified server.

If the function fails, it returns a handle that is not valid. You can test the validity of the handle by using it in another function call.


When you have finished using the handle returned by WTSOpenServer, release it by calling the WTSCloseServer function.

You do not need to open a handle for operations performed on the RD Session Host server on which your application is running. Use the constant WTS_CURRENT_SERVER_HANDLE instead.


The wtsapi32.h header defines WTSOpenServer 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.
