Inter-thread communication (worker threads)

Question

I\'ve created two threads A & B using CreateThread windows API. I\'m trying to send the data from thread A to B.

I know I can use Event object and wait for the Event

Answer 1

Since the two threads are in the same process (at least that's what it sounds like), then it is not necessary to "send" data. They can share it (e.g., a simple global variable). You do need to synchronize access to it via either an event, semaphore, mutex, etc.

Depending on what you are doing, it can be very simple.

Thread1Func() {
  Set some global data
  Signal semaphore to indicate it is available
}

Thread2Func() {
  WaitForSingleObject to check/wait if data is available
  use the data
}
