# wxCriticalSectionLocker Class Reference
[Threading]

`#include <wx/thread.h>`

## Detailed Description

This is a small helper class to be used with wxCriticalSection objects.

A wxCriticalSectionLocker enters the critical section in the constructor and leaves it in the destructor making it much more difficult to forget to leave a critical section (which, in general, will lead to serious and difficult to debug problems).

Example of using it:

        void Set Foo()
        {
            // gs_critSect is some (global) critical section guarding access to the
            // object "foo"
            wxCriticalSectionLocker locker(gs_critSect);

            if ( ... )
            {
                // do something
                ...

                return;
            }

            // do something else
            ...

            return;
        }

Without wxCriticalSectionLocker, you would need to remember to manually leave the critical section before each `return`.
