pthread_rwlock* for IPC on shared mem

I’d like to use the pthread_rwlock* fn’s on shared mem…

i am guessing that since pthread_rwlockattr_setpshared() exists… that it should work…

But i havent’ found any other supporting doc/howtos on the qnx website.

I think the general idea would be to put the pthread_rwlock_t rwl object into the shared mem so the other process can see it and call pthread_rwlock calls with &shared.rwl,

Anyone tried this?
