Hi, I like using boost threads, but I'm currently working on a project where I need to access the private handle to the underlying system thread (in the cases I'm concerned about, the pthread_t). This is so that I can take advantage of platform-specific functionality, such as setting CPU affinity and (more generally) calling into other libraries that expect a pthread_t. Is there any way to do get this handle?

Thanks!

class thread { public: ... typedef platform-specific-type native_handle_type; native_handle_type native_handle(); ... };

I haven't used it myself though.

Hmm. Looking at the source, this doesn't actually seem to be in there...at least not in the latest release (1.35).

It's there for Win32 and not for pthreads. I'll add it for pthreads on trunk.

I see.

While you're at it, would you mind also adding it uniformly to all the other threading primitives (mutex, etc.)?

There isn't always a valid mapping (e.g. condition_variable_any, timed_mutex), but I intend to add it where possible.
