Enumeration Type Documentation

◆ EEmptyGuard

class CGuard<> implements a templatized "resource acquisition is initialization" (RAII) locking guard.

This guard is useful for locking resources in an exception-safe manner. The classic use of this is to lock a mutex within a C++ scope, as follows:

void SomeFunction() { CGuard<CMutex> GUARD(some_mutex); [...perform some thread-safe operations...] }

If an exception is thrown during the performance of any operations while the guard is held, the guarantee of C++ stack-unwinding will force the guard's destructor to release whatever resources were acquired.
