 /**

    A convenience postfix macro that is equivalent to wrapping the

    preceding expression with User::LeaveIfError().

    The code:

    @code

    fs.Connect() OR_LEAVE;

    @endcode

    is equivalent to:

    @code

    User::LeaveIfError(fs.Connect());

    @endcode

    The implementation happens to rely on overloading operator|| for

    TLeave. However, this macro is not intended for use within general

    expressions, just to guard individual calls to methods that may

    return an error code.

 #define OR_LEAVE || ELeave

 /**

    Enabling overload for OR_LEAVE. Should only be invoked via

    OR_LEAVE, never directly.

  */

 inline void operator||(TInt aStatus, TLeave /*aTag*/)

 	User::LeaveIfError(aStatus);
