[gtkmm] Glib::Module API issues

[Ross Burton <r burton 180sw com>]

Hi,

I'm using Glib::Module to load C++ objects from .so files at runtime --
the good news is that it works.  However, there appears to be a problem
with the wrapping.

The C API is:

GModule* g_module_open (const gchar *file_name, GModuleFlags flags);

Returns a GModule*, or NULL on failure.

However, the C++ API:

Glib::Module::Module (const std::string& file_name, ModuleFlags flags);

If I use the constructor directly, I can't have a null GModule on the
stack. If I use new, then I don't seem to get a null pointer even if I
try and load a module which doesn't exist.

I've compared module.hg and gtk/window.hg, and the way they declare the
constructor wrapping is totally different. Of course, not being a gtkmm
wrapping wizzard, this could be intentional. But as Glib::Module isn't a
commonly used class, I guess this sort of bug could have gone unnoticed.

So, is there a bug in the wrapping? Or am I going mad...

Regards,
Ross
