> Does Sun CC compiler below supports the pthread_rwlock_* calls? Compiler itself shouldn't have any special features to support pthreads; pthread.h is Solaris header file. BTW, did you include it? And which version of Solaris do you have?

And yes, "pthread.h" is included. It does not have declarations for "pthread_rwlock_*" functions.

Looks like those functions are not only missing from pthread.h, but from libpthread.so too.

$ nm /usr/lib/libpthread.so.1 | grep pthread_rwlock

(nothing here)

The fact that those functions are not in the header means that they are not supported in Solaris 6. Next version of the OS, Solaris 7, provides these functions.
