Robert, The load_single_library method is a convenience method for a common case. In general, I recommend using a shared_library object instead. I believe this case is detailed in the latest documentation. However, you are probably right that I need to change the load_single_library function to either return a bool or throw an exception. Thanks for the heads up, and sorry about the time lost debugging. Jeremy On Thu, Jul 3, 2008 at 4:15 PM, Robert Dailey <rcdailey@gmail.com> wrote:
When calling load_single_library(), if the 3rd parameter, which is the name of the export factory function, is incorrect, load_single_library() will silently fail and return as if nothing went wrong. However, since the name of that function was mistyped (in my case), I had to debug into the boost.extensions library to figure out the actual source of the problem. I think this should have thrown an exception.
For example, I called the function like below:
factory_map fm; load_single_library( fm, "my_library.dll", "my_export_method_typo" );
And my function, as defined in the DLL source, is as follows:
extern "C" void BOOST_EXTENSION_EXPORT_DECL my_export_method( boost::extensions::factory_map& fm ) { }
As you can see, the string (in the first code example) is clearly mistyped/misnamed. This results in silent failure. Opinions on this would be useful. _______________________________________________ Unsubscribe & other changes: http://lists.boost.org/mailman/listinfo.cgi/boost
