Detailed Description
Link support run-time API, all link types provide an lset which is used by the IOC database to control and operate the link. This file also declares the dbLink routines that IOC, record and device code can call to perform link operations.
Definition in file dbLink.h.
Typedef Documentation
◆ dbLinkUserCallback
| typedef long(* dbLinkUserCallback) (struct link *plink, void *priv) |
Called by the lset::doLocked method to permit multiple link operations while the link instance is locked.
- Parameters
-
plink the link priv context for the callback routine
