// Abstract :
|
||
|
|
//
|
||
|
|
// This is the definition of the CLock class. This class was created in order to
|
||
|
|
// support automatic destruction of C++ object when an exception is thrown.
|
||
|
|
//
|
||
|
|
// Note :
|
||
|
|
//
|
||
|
|
// The CLock class is not thread safe (although the CCriticalSection class is). The CLock
|
||
|
|
// class should be used as a local variable when locking using a CCriticalSection object.
|
||
|
|
// This is done in order to warranty that all locks on an object are released when an
|
||
|
|
// exception is thrown.
