Can you expand on what's wrong with initHooks?
Couldn't you create a linked list of the device private structures for your devices with a file-static pointer to the list -- then the initHooks routine could traverse this list at whatever points you need during IOC initialization.

I would like to use something like the EPICS initHookFunction.  The problem with it is that it is a static function with no mechanism that I see to pass to it a pointer to my device driver class object, so that from the callback routine the correct instance of the device driver can be called.  I have a situation where I have a few identical VME ADC boards and for each of these boards I create an object of the class (derived from asynPortDriver).
