Darryl brings up a good point.
What I should say about the OM API is that it is deprecated, i.e., it is
supported on Solaris at least, but all new application should be written to
FoxAPI instead.
You will note that the OM header files do not exist for NT to help
"encourage" the shift to FoxAPI.

Some examples of using omlists and dqchange would be good. I
remember
trying to get event driven changes to go some years ago without
success.
The example in the manual didn't work (If my memory is correct).
Polling
the list worked Ok though and got me out of the hole at the time.
