Shared pthread mutex and condition variables

[Sad Clouds <cryintothebluesky%googlemail.com@localhost>]

NetBSD is missing the following functions

pthread_mutexattr_setpshared()
pthread_mutexattr_setpshared()
pthread_condattr_setpshared()
pthread_condattr_getpshared()

So I take it there is no way to have multiple unrelated processes to share the 
same mutex/condition variable?
