/* The glwthread_thread_t is a pointer to a structure in memory.
|
|
Why not the thread handle? If it were the thread handle, it would be hard
|
|
to implement glwthread_thread_self() (since GetCurrentThread () returns a
|
|
pseudo-handle, DuplicateHandle (GetCurrentThread ()) returns a handle that
|
|
must be closed afterwards, and there is no function for quickly retrieving
|
|
a thread handle from its id).
|
|
Why not the thread id? I tried it. It did not work: Sometimes ids appeared
|
|
that did not belong to running threads, and glthread_join failed with ESRCH.
