CComCriticalSection::Lock

 

Calls the Win32 function EnterCriticalSection, which waits until the thread can take ownership of the critical section object contained in the m_sec data member.

Copy 

HRESULT Lock( ) throw( );

Returns S_OK on success, E_OUTOFMEMORY or E_FAIL on failure.

The critical section object must first be initialized with a call to the Init method. When the protected code has finished executing, the thread must call Unlock to release ownership of the critical section.
