Hi Dirk,

Sounds great. Thank you so much. I'll take a look into the busyRecord.

Subject: Way to know when streamReload has been completed

 

Hi Andy,

When the function returns it has finished its work, i.e. all currently running protocols have beeb aborted and all records have re-read their protocol files. At that time, the sub record finishes processing. Thus, you can write using a caput with callback. When it returns, all work is done.

If you (i.e. the CA client you are using) have no callback option, then you can FLNK some records together to set some record to 1, then call streamReload and from there FLNK to a record that writes 0.

Maybe you can use the busyRecord somehow, but I have never tried that.

Hi all,

I've been using streamReload in both the IOC shell and inside an aSub function.  I have noticed that as streamReload executes, it causes a message to appear in the IOC Shell listing which records have just been reloaded. When the messages stop, I assume that is when streamReload has completed. I was wondering if there was a way to know when it has completed through a function of some sort that returns a value corresponding to the state of streamReload. The reason I ask is because if the operator does proceed with using streamReload on the Control Systems GUI, I would like there to be an indicator that shows grey when streamReload is executing and green when it has completed.

Thank you,

Andy
