GetThreadDesktop
The
GetThreadDesktop function returns a handle to the desktop associated with a specified thread.
HDESK GetThreadDesktop(
DWORD dwThreadId
| // thread identifier
|
);
|
|
Parameters
dwThreadId
Identifies the thread for which to return the desktop handle. The
GetCurrentThreadId and
CreateProcess functions return thread identifiers.
Return Values
If the function succeeds, the return value is the handle of the desktop
associated with the specified thread.
Remarks
The system associates a desktop with a thread when that thread is created. A
thread can use the
SetThreadDesktop function to change its desktop. The desktop associated with a thread must be
on the window station associated with the thread's process.
The calling process can use the returned handle in calls to the
GetUserObjectInformation,
GetUserObjectSecurity,
SetUserObjectInformation, and
SetUserObjectSecurity functions.
Windows 95: Windows 95 does not support multiple desktops, so
GetThreadDesktop always returns the same value.
