Many Web Services Client for C++ methods either expect or create
memory objects.
Below is a list of rules that you must follow when developing web
service client applications:
v Any memory object that is passed to Web Services Client for C++ does
not need to persist past the method for which it was required and
should be deleted at the earliest opportunity.
v Any memory object created and returned by Web Services Client for
C++ should be deleted by the client application before the deletion of
the web service that created it. Note that Windows requires that the
memory object be deleted from within the thread that created it,
otherwise you may get an out of bounds exception type error from the
core C++ libraries.
v Any object passed by reference (rather than value) that is used by
Web Services Client for C++ must be created using new, and destroyed
using delete.
v Once an object has been deleted, its pointer must be set to NULL
(this is to ensure that the pointer is not used elsewhere).
Hi John,
Would it be useful to have some information included into this list
on what types of return values returned by clients are expected to be
deleted?
e.g. All complex types returned are allocated by the client stub and
should be deleted by the user program. The destructor of the complex
type would take care of its members. All basic types are returned by
value and thus need no memory cleaning.
All nillable values are returned as pointers, and thus should
be cleaned by calling program.
Also, what happens with arrays, I think you have changed the
memory model for this by now.
Would the above make sense?
Thanks,
Samisa..

Memory management
Does the client need to delete the memory associated with the return
objects returned by the generated webservice methods? Or is the
memory managed by the axis?
