[thread] Obtaining thread id on Windows
I'm using Boost.Thread to create a thread that process the message queue on Windows. In order to send it a message via PostThreadMessage I need a thread id rather than a handle. Is there a way to obtain the native thread id from a boost::thread ? If not, any help on how to patch my local copy of the library? There is no documented way of getting a thread id from a thread handle in Windows XP. Thank you. Agustín K-ballo Bergé.-

From within the thread, you may be able to use ::GetCurrentThreadId()

If you cannot store the thread ID when the thread is created, the best way (in my experience) to get the thread ID is to have the thread itself store it in a predetermined location when the thread starts up (using Ray's suggestion of GetCurrentThreadId()). John

If you have a window associated with the thread, then you can use the easier function GetWindowThreadProcessId. Otherwise you can use NtQueryInformationThread, although it may be simpler to store the thread ID on creation. See http://www.codeguru.com/forum/showthread.php?t=355572 for an example using NtQueryInformationThread. It's a good guess that GetThreadId is a wrapper for NtQueryInformationThread. -- Bill --

If you mean Win API, there's GetThreadID(handle) function.
Such function does not exist on Windows XP. There is no documented way on Windows XP. Here is some more information: http://social.msdn.microsoft.com/Forums/en-US/vcgeneral/thread/89728ee1-d9d8... Agustín K-ballo Bergé.-
