Subject: Support for larger messages in IOC Error Logging facility
From: "J. Lewis Muir" <[email protected]>

I have a situation where I would like to log messages via the IOC Error Logging facility (e.g. errlogPrintf) that are longer than the current maximum message size of 256 characters (as of EPICS 3.14.8.2).

I see that I probably could change MAX_MESSAGE_SIZE in EPICS base at

src/libCom/error/errlog.c

but I'd rather not be running a modified EPICS base.

As a work around, I could break up the longer messages into smaller pieces, logging each piece individually, but I would rather not. Is there a better way to handle this?

Or if I submitted a patch to allow a larger message size perhaps by changing the errlogInit function to allow a second argument of "int msgsize", would it likely be accepted or are there reasons against this?

Thanks,

J. Lewis Muir
