Antonio,
I'm already doing the callback in a custom way using IupLoopStepWait().
The following is how I'm now doing my .50 cent callbacks now. My goal
now that I have multi-threading working in the console interpreter and
not only the web server, a direct callback to the SB call function
embeddng API. (like what Charles is doing with DLLC but Windows only)

*** C Interface ***
besFUNCTION(PuiSetCallback)
Ihandle *ih;
const char *name;
char *class_name;
besARGUMENTS("pz")
&ih, &name
besARGEND
class_name = IupGetClassName(ih);
if (strcmp(class_name, "dialog") == 0) {
IupSetCallback(ih, name, (Icallback)&WinEvent);
}
else if (strcmp(class_name, "button") == 0) {
IupSetCallback(ih, name, (Icallback)&BtnEvent);
}
else if (strcmp(class_name, "list") == 0) {
IupSetCallback(ih, name, (Icallback)&ListEvent);
}
else {
IupSetCallback(ih, name, (Icallback)&Event);
}
besRETURN_STRING(class_name);
