How to use anonymous pipes in windows api (and pass to gtk function)?

Question

I need to be able to pass int value representing fd (pipe fd) to gtk function as a first parameter

gint gdk_input_add gint source,
         GdkInputCondition condition,
         GdkInputFunction function,
                       gpointer data);

How do I do that, as CreatePipe returns HANDLE which is NOT int?

Thanks

Answer 1

To convert a HANDLE value to a C file descriptor, call _open_osfhandle.
