--- This package provides routines for accessing the most recently raised

--- also be useful for mimicing implementation dependent capabilities in
--- Ada 83 compilers, but see also GNAT.Current_Exceptions for this usage.

- -- Subprograms --
- -----------------
-
- function Occurrence
- return Ada.Exceptions.Exception_Occurrence;
- -- Returns the Exception_Occurrence for the most recently raised
- -- exception in the current task. If no exception has been raised
- -- in the current task prior to the call, returns Null_Occurrence.
-
- function Occurrence_Access
- return Ada.Exceptions.Exception_Occurrence_Access;
- -- Similar to the above, but returns an access to the occurrence value.
- -- This value is in a task specific location, and may be validly accessed
- -- as long as no further exception is raised in the calling task.
-
- -- Note: unlike the routines in GNAT.Current_Exception, these functions
- -- access the most recently raised exception, regardless of where they
- -- are called. Consider the following example:
-
- -- exception
- -- when Constraint_Error =>
- -- begin
- -- ...
- -- exception
- -- when Tasking_Error => ...
- -- end;
- --
- -- -- Assuming a Tasking_Error was raised in the inner block,
- -- -- a call to GNAT.Most_Recent_Exception.Occurrence will
- -- -- return information about this Tasking_Error exception,
- -- -- not about the Constraint_Error exception being handled
- -- -- by the current handler code.
