CATCH_ALL

Article
12/01/2015

Defines a block of code that catches all exception types thrown in the preceding TRY block.

Syntax

CATCH_ALL(
exception_object_pointer_name )

Parameters

exception_object_pointer_name
Specifies a name for an exception-object pointer that will be created by the macro. You can use the pointer name to access the exception object within the CATCH_ALL block. This variable is declared for you.

Remarks

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.

Note

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.
