How to find out if a thread has message queue?

c++, message, message-queue, winapi, windows

Solution

You can use PostThreadMessage with the ID of the thread. If PostThreadMessage returns false and GetLastError returns `ERROR_INVALID_THREAD_ID`, the thread ID is invalid or the thread does not have a message queue.

Problem

Is there any way to find out from threadId , if a thread has message queue or not? Basically there are some windows api which only work if a thread has message queue.window
