I have been trying to move some OT networking code to Carbon and find that
I crash as soon as my YieldingNotifier is called. The code I am recompiling
worked fine under OS 9.2.2. and was compiled uisng MW CW 6.
Carbon code that installs an OT notifier must pass in a UPP (an
OTNotifyUPP), created using NewOTNotifyUPP. An OTNotifyUPP is just a
simple function pointer on traditional Mac OS and on Mac OS X when
you're built Mach-O. However, if you're running on Mac OS X and
you're built CFM, an OTNotifyUPP wraps the glue that allows the
Mach-O Open Transport compatibility library to call back to your CFM
notifier.
So, instead of:
err = OTInstallNotifier(ep, YieldingNotifier, NULL);
you would use:
static OTNotifyUPP gYieldingNotifierUPP = NULL;
if (gYieldingNotifierUPP == NULL) {
gYieldingNotifierUPP = NewOTNotifyUPP(YieldingNotifier);
}
err = OTInstallNotifier(ep, gYieldingNotifierUPP, NULL);
