The CleanupClosePushL() templated function constructs and pushes a TCleanupItem onto the cleanup stack.
The CleanupClosePushL() templated function constructs
and pushes a TCleanupItem onto the cleanup stack. When CleanupStack::PopAndDestroy() is
called, the Close() member function of the object encapsulated
by the TCleanupItem is called.
... RTestTwo two; CleanupClosePushL(two); ... CleanupStack::PopAndDestroy(); ...
The TCleanupItem object encapsulates a reference to the RTestTwo object;
the cleanup operation is the static function Close() of the
templated class CleanupClose<class T>. This is
implemented by simply calling the Close() member function
of RTestTwo. This means that RTestTwo must
define or inherit a member function Close() which performs
whatever clean up is required.
