Detailed Description

Wraps the readers/writers mutex implementation on your platform.

Note
A readers/writers mutex is a mutex that can be locked in two differing ways:
  • A read-lock: Prevents other threads from obtaining a write-lock, but not other read-locks.
  • A write-lock: Prevents other threads from obtaining either a read-lock or write-lock.

Usually, if a thread attempts to aquire a write-lock while read-locks are being held, this will prevent any further read-locks from being obtained, until the write-lock is aquired and released. This prevents the "writer starvation" problem.
