Re: How do we use the GtkPlug and GtkSocket using threads without a fork() call?

["Robert E. Hartley" <rhartley ics com>]

Hi,

Does this mean it is impossible and that nobody knows how to do it?

I keep asking periodically, but I never get a final answer as to whether this has
been done before.

Basically, I want to avoid reinventing the wheel, but if this is something new,
please let me know so that I can get the "go-ahead" to work on it.

Thanks for your help either way,

Robert
