CAutoLock Class

The CAutoLock class holds a critical section for the scope of a code block.

This class works in conjunction with the CCritSec class, which is a wrapper for critical section objects. The CAutoLock constructor locks the critical section, and the destructor unlocks it. By using a CAutoLock object as a local variable, you can lock a critical section with the guarantee that all code paths will unlock the critical section.

The following code example shows how to use this class:

CCritSec csMyLock;  // Critical section is not locked yet.
{
    CAutoLock cObjectLock(&csMyLock);  // Lock the critical section.

    // Protected section of code.     

} // Lock goes out of scope here.

The methods in this class are not designed to be overridden.

Requirements

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

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