Remarks

CComCriticalSection is similar to class CComAutoCriticalSection, except that you must explicitly initialize and release the critical section.

Typically, you use CComCriticalSection through the typedef name CriticalSection. This name references CComCriticalSection when CComMultiThreadModel is being used.

See CComCritSecLock Class for a safer way to use this class than calling Lock and Unlock directly.
