WTSLogoffSession function (wtsapi32.h)
Logs off a specified Remote Desktop Services session.
Syntax
BOOL WTSLogoffSession(
[in] HANDLE hServer,
[in] DWORD SessionId,
[in] BOOL bWait
);
Parameters
[in] hServer
A handle to an RD Session Host server. Specify a handle opened by the WTSOpenServer or WTSOpenServerEx function, or specify WTS_CURRENT_SERVER_HANDLE to indicate the RD Session Host server on which your application is running.
[in] SessionId
A Remote Desktop Services session identifier. To indicate the current session, specify WTS_CURRENT_SESSION. You can use the WTSEnumerateSessions function to retrieve the identifiers of all sessions on a specified RD Session Host server.
To be able to log off another user's session, you need to have the Reset permission. For more information, see Remote Desktop Services Permissions. To modify permissions on a session, use the Remote Desktop Services Configuration administrative tool.
To log off sessions running on a virtual machine hosted on a RD Virtualization Host server, you must be a member of the Administrators group on the RD Virtualization Host server.
[in] bWait
Indicates whether the operation is synchronous.
If bWait is TRUE, the function returns when the session is logged off.
If bWait is FALSE, the function returns immediately. To verify that the session has been logged off, specify the session identifier in a call to the WTSQuerySessionInformation function. WTSQuerySessionInformation returns zero if the session is logged off.
Return value
If the function succeeds, the return value is a nonzero value.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
