need help with WaitForSingleObject

i cant seem to understand this API from msdn
what does signed and unsigned states mean exactly
can anyone do me a small example without threads involved

There are actually signalled and unsignalled states.

http://msdn.microsoft.com/library/de...ngleobject.asp
http://msdn.microsoft.com/library/de..._processes.asp

yes i dont really understand what it means by those ,

Well different kernel objects enter a signaled state under different conditions

Threads - when they terminate
Events - when the user sets an event

All sortsa stuff

http://msdn.microsoft.com/library/de...re_objects.asp
http://msdn.microsoft.com/library/de..._a_process.asp

etc.

Bit more info here:
Synchronization Objects

I like how authorative you are anonytmouse. Passive, but authorative.
