Hello Philippe,
Of course, it'd be nice to check the EL at CT to see if they
correspond to func parameters types.
The call inside check will coever that for you as long as you don't mind
getting the error in an odd place.

It shouldn't be too difficult to inject an extra parameter; just add it
to the end of the call to the wrapped function after args.

Hi folks,
I'd like to wrap a family of C functions that look like this:
gboolean fooXXX(arg1, ..., argN, GError** err)
Their signatures and arities vary, but they all have a GError** as
their last argument. If a function returns false, then 'err' will be
set to a relevant Error struct.
