CCritSec Class

The CCritSec class provides a thread lock.

This class is a wrapper for a critical section. You can lock and unlock the thread by calling the CCritSec::Lock and CCritSec::Unlock methods. However, it is safer to use this class in conjunction with the CAutoLock class. When the CAutoLock class goes out of scope, it automatically unlocks the CCritSec object. Moreover, it compiles to efficient inline code.

Requirements

**  Header:** Declared in Wxutil.h; include Streams.h.

**  Library:** Use Strmbase.lib (retail builds) or Strmbasd.lib (debug builds).
