C++ exception (and generic) stack trace debug library
process & csdbg::process::cleanup_thread ( pthread_t  id)

Cleanup libcsdbg-related thread resources upon thread cancellation.

[in]idthe thread ID
This method should be called from thread cancellation handlers to release resources. If you don't cleanup the thread handle though it becomes useless when the actual thread has exited, it continues to occupy memory and will also inject junk, empty traces in dumps or in explicit trace requests
