Yes, use the pstack command.  I think it's available on both systems.

Accessing that kind of information directly is done through the proc
pseudo filesystem which is platform dependent if it exists at all.
You'll find different information on different platforms.  The thread
ids in proc are the kernel ids and don't necessarily correspond to
pthread ids.  You need to find a mechanism to translate from one to the
other.  For linux, it's the gettid syscall and it's just a kernel thread
id version of pthread_self() IIRC.
