Defines a block of code that catches all exception types thrown in the preceding TRY block.
The exception-processing code can interrogate the exception object, if appropriate, to get more information about the specific cause of the exception. Invoke the THROW_LAST macro to shift processing to the next outer exception frame. If you use CATCH_ALL, end the TRY block with an END_CATCH_ALL macro.
The CATCH_ALL block is defined as a C++ scope delineated by braces. If you declare variables in this scope, they are accessible only within that scope.
