There seem to be other C or C++ language compatible thread packages
besides the standard POSIX 1003.1-2001 thread-related system calls.
For instance Qt implements some thread class code. I would imagine
that implementations which use kernel threads as opposed to user
threads would be based on the POSIX calls. Is this correct? What
other thread packages are available besides the POSIX ones? Just
speculating. Which packages are kernel thread based and which
ones are user thread based?
Thank you for your feedback,
