Applications Programming

I need help!Many Thanks!
Now,I try to manage the shared memory inter-process .
Inevitably,I have to deal with the synchronous.
I know the pthread_rwlock in posix,and I compile ,then run successfully in Red Hat Enterprise 4.
I have a doubt about whether the Posix supports the system such as HP_UX,AIX and others.

(sorry for my poor English)
