This is a far-fetched question, but I was wondering whether there is a possibility of executing streamReload, or a similar functionality, within a C function. The reason why I ask is because I saw within this Github link (https://github.com/epics-modules/ioczed/blob/master/zzzApp/Db/streamExample.db <https://github.com/epics-modules/ioczed/blob/master/zzzApp/Db/streamExample.db>) that the SUB record calls streamReload. However, I couldn’t locate the source code for that, so I am not entirely sure how it is used and what its arguments are. Thoughts?

The registrar code adding both the function callable
from subRecord as well as iocsh.

https://github.com/paulscherrerinstitute/StreamDevice/blob/dfbd308d4602e7cb99d7f60ddf35909a70f41c4f/src/StreamEpics.cc#L297-L307

So you could do something like

iocshCmd("streamReload");

cf. iocsh.h from Base.

Since it is already callable from a subRecord I assume
it is thread-safe.
