I am trying to set Thread Affinity using SetThreadAffinityMask function imported from kernel32.dll in C # code of mine.

This is how I import SetThreadAffinityMask function from "kernel32.dll" in my C# .net code

 [DllImport("kernel32.dll")]  
 static extern IntPtr SetThreadAffinityMask(IntPtr hThread, IntPtr dwThreadAffinityMask);

I am creating 3 threads

    Thread t1=new Thread(some delegate);
    Thread t2=new Thread(some delegate);
    Thread t3=new Thread(some delegate);

I wish to set Thread affinity for t1,t2 & t3 for which I am using SetThreadAffinityMask function.

But I am not getting how to pass parameters to this function.

SetThreadAffinityMask takes two parameters

1. HANDLE hThread
2. DWORD_PTR dwThreadAffinityMask

Please help me in using SetThreadAffinityMask function in C#

Thanks in advance !
