Hello, everyone,
I made a record support for our special needs. There are 2 arrays in this
record support, and I wish to read them from host caget. We are using
base3.13.8.
The definitions for these fields in the dbd file are:
field(BCME,DBF_NOACCESS) {
prompt("BCM readout for BER")
extra("char bcme[402] ")
asl(ASL1)
special(SPC_DBADDR)
interest(3)
}
field(BCMP,DBF_NOACCESS) {
prompt("BCM readout for BER")
extra("char bcmp[402] ")
asl(ASL1)
special(SPC_DBADDR)
interest(3)
}
But whenever I caget one of these fields, the cvt_dbaddr is called twice. Is
it normally called twice? What's the possible problem in my codes?
static long cvt_dbaddr(paddr)
struct dbAddr *paddr;
{
struct bktRecord *pbkt=(struct bktRecord *)paddr->precord;
struct bktdset *pdset = (struct bktdset *)(pbkt->dset);
if (bkt_debug>3) {
printf("cvt_dbaddr\n");
printf("pbkt bcme, %u, bcmp, %u\n", (long)pbkt->bcme, (long)pbkt-
>bcmp);
printf("paddr pfield %u\n", paddr->pfield);
}
if ( ((long)paddr->pfield)==((long)pbkt->bcme) ) {
if (bkt_debug>1) printf("cvt_dbaddr for bcme\n");
(*pdset->read_rfm)(pbkt);
} else if ( ((long)paddr->pfield)==((long)pbkt->bcmp) ) {
if (bkt_debug>1) printf("cvt_dbaddr for bcmp\n");
(*pdset->read_rfm)(pbkt);
} else printf("cvt_dbaddr, where is it called?\n");
/* paddr->pfield = (void *)(pbkt->bcme); */
paddr->no_elements = 402;
paddr->field_type = DBF_CHAR;
paddr->field_size = 1;
paddr->dbr_field_type = DBF_CHAR;
return(0);
}
Thank you all,
Ge
