Detailed Description

Proxy for acquiring, renewing, and releasing a distributed readers lock.

This is the remote equivalent to ACE_Local_RLock. Multiple readers can hold the lock simultaneously when no writers have the lock. Alternatively, when a writer holds the lock, no other participants (readers or writers) may hold the lock. ACE_Remote_RLock depends on the ACE Token Server for its distributed synchronization semantics.
