Detailed Description

Implementation of RWLock for Pthread mutexes.

Member Function Documentation

virtual bool net_instaweb::PthreadRWLock::ReaderTryLock ( )

virtual

ReaderLock/Unlock are different from normal locks. Reader locks are shared while normal locks are exclusive. Normal lock cannot happen when reader has a lock. Try to acquire a read share of this lock without blocking.

Implements net_instaweb::ThreadSystem::RWLock.
