Experimental Physics and Industrial Control System
I'm failing to come up with a clever way of replacing
dbGetPdbAddrFromLink, which was removed in base 3.15. It was defined
as a macro in dbAccessDefs.h as this:
#define dbGetPdbAddrFromLink(PLNK) \
( ( (PLNK)->type != DB_LINK ) \
? 0 \
: ( ( (struct dbAddr *)( (PLNK)->value.pv_link.pvt) ) ) )
I can redefine this macro in my source code as the above, but is there
a better way of replacing its functionality, perhaps with a different
macro or function call?
Here's an example of how we were using it:
...
DBADDR *cntAddr = dbGetPdbAddrFromLink(&psub->inpi);
short *cntP;
long cntNord, offset;
struct rset *prset;
if (!cntAddr) return -1;
dbScanLock(cntAddr->precord);
if ((cntAddr->field_type == DBF_SHORT) && ((prset = dbGetRset(cntAddr)))) {
cntP = (short *)cntAddr->pfield;
if (!cntP) cntNord = 0;
else (*prset->get_array_info)(cntAddr, &cntNord, &offset);
} else {
cntP = 0;
cntNord = 0;
}
dbScanUnlock(cntAddr->precord);
...
This is for some rather critical systems, so we're trying at all costs
to avoid surprise runtime errors.
Any suggestions are much appreciated.
