Drew, don't do that! As long as the record is attached to a database,
there had better be a valid handle for it.
To answer the original question: when you use DmGetRecord, you use
DmReleaseRecord when you're done with it. DmGetRecord marks the record
as busy and returns the record handle. DmReleaseRecord marks the record
as not busy. If you don't intend to change the record, you can use
DmQueryRecord instead of DmGetRecord, and then you don't need to (in
fact, you should not) use DmReleaseRecord.
If you want to completely dispose of a record, use DmDeleteRecord or
DmRemoveRecord. They both detach the record from the database, making
it safe to then delete the record's handle. The difference is that
DmDeleteRecord waits until the next HotSync to actually delete the
handle, but DmRemoveRecord deletes the handle immediately.
