Experimental Physics and Industrial Control System
This finally got to the top of my TODO list.
There was a lot of discussion about how to implement this feature.
The main ideas were:
1) Provide a field RTYP in every record.
2) Provide a new Channel Access Request type.
I agree with the second alternative.
Jeff Hill suggested that we have a new request type DBR_CLASS_NAME.
For example:
char classname[80];
...
SEVCHK(ca_get(DBR_CLASS_NAME,mychid,&classname),"ca_get");
SEVCHK(ca_pend_io(waitTime),"ca_pend_io");
printf("pv: %s classname %s\n",ca_name(mychid),classname);
I modifyied db_access.h, db_access.c, and the ca/convert.c to implement
the change. Jeff will still have to look to see if any other channel
access changes are necessary if new clients talk to old servers.
