How should we proceed?

This cleanup was my doing. The main goal was to fix some inconsistencies in the API (not all functions used the jump table). This allows the null implementation to actually link for targets other than RTEMS/vxWorks.

It also makes it possible to compile in multiple implementations and choose one at runtime. This was handy once when lack of hardware access forced me to develop against a simulated device.

Hopefully the changes we made should not require too much in the way of
modifications to your implementation.

If you're only replicating the vxWorks API (and simply copying the vxWorks version of devLibVMEOSD.c to src/libCom/osi/os/Linux/) then I'm surprised you have problems. The usage of the vxWorks API hasn't changed.

I'm happy to help you work through these problems. It might be best to take this process off the mailing list.


Michael
