DWORD WINAPI GetCurrentThreadId(void);

DWORD WINAPI GetThreadId(
  __in  HANDLE Thread
);
      

The pthread_equal function is used to compare the thread IDs of two threads. It will return a non-zero value if the two are equal and a zero value if they are not.

In the Windows threading model a thread has a HANDLE which is the normal method by which the object is manipulated. In addition to its handle each thread in the system has a system-wide unique id which can be accessed with the GetThreadId and GetCurrentThreadID functions. While there is no direct single call to match the POSIX pthread_equal function, a simple numeric compare after making the two get thread id calls would achieve the same result.
