As with all of the other pthread structures, POSIX says that the
structure itself is opaque.  The values in the attribute can be set
using the pthread_rwlock_attr_* functions.  Currently the only two are:

pthread_rwlockattr_setpshared()
pthread_rwlockattr_getpshared()

Which set or get whether the lock is shared by more than one process.

Beyond this, the structure is only used in pthread_rwlock_init() to
setup a new rwlock.
