WaitHandle.WaitAny to match WaitForMultipleObjects functionality

Question

I am porting C++ API code to .NET and looking into function call WaitHandle.WaitAny as a replacement for WaitForMultipleObjects but when debugging with .NET4 i can see that this function is hooked into

private static extern int WaitMultiple(
                               WaitHandle[] waitableSafeHandle, 
                               int msTimeOut, 
                               bool exitContext, 
                               bool WaitAll);

and this makes me think that this function is not sutable for the port. Any other suggestions?

Answer 1

It is true that WaitHandle.WaitAny() is not quite enough to match the functionality of WaitForMultipleObjects(). But you just need to use WaitHandle.WaitAll() as well.

• WaitHandle.WaitAny() matches WaitForMultipleObjects() called with the WaitAll parameter set to FALSE,.
• WaitHandle.WaitAll() matches it with WaitAll set to TRUE.
