RE: monitors for arrays

["Eric Bjorklund, NPSM" <BJO@accr.lcs.lanl.gov>]

Brian,

I ran into this same problem on one of my own custom records.  The trick
is that the 2nd parameter of db_post_events should be the address of the
*data* (usually this is the same as the address of the field, but not for
SPC_DBADDR fields).

Hope this helps.

Eric Bj.
