Are these apis?

Can someone tell me if these are apis and if they are what do they do:
DestroyWindow
ExitWindowsEx
BroadcastSystemMessage
ActivateKeyboardLayout
CloseDesktop

They are API calls. I'm not sure what they do, but get the API viewer (link in my signature). It is a great program.

DestroyWindow - Sends a message to the window in response to which it is destroyed.

ExitWindowsEx - Shuts down windows. Depending on the parameter passed, can logoff

BroadcastSystemMessage - Send a system wide message to all the main application windows. For example, you could broadcast a WM_POWERMANAGEMENT message top tell the applications that windows is supsending.

ActivateKeyboardLayout - Makes one of the installed keyboard layouts the active one...


CloseDesktop - Closes a handle to a desktop, which you have opened with OpenDesktop or CreateDesktop - see ApiDesktop class for more on what you can do with this...

HTH,

Allapi.net don't seem to have got round to CloseDesktop yet - which is a shame as I could have used some extra info on managing desktops and winstations rathyer than having to work it out by trial, GPF and retrial :D
