Hi Emmanuel,

This looks strange. Are you sure that your link has the correct type,
e.g. INST_IO, not CONSTANT, PV_LINK or CA_LINK or something like this?

Do you check psi->inp.type before you parse the value?

Do 'dbpr "recordname",1' and check the type of the INP link.

Check your .dbd file, too.

Hello,

For a few of my soft records, I used to read the INP field directly with a command like

[driver code]

myStatus=sscanf(psi->inp.value.instio.string, "@lm=%d df=%[^\n]",
                  &myLogMark, p_myDateFormat);

[/driver code]

It turns out this method doesn't work correctly anymore.
Indeed the psi->inp.value.instio.string is truncated at the first 'space' char.
In my case, that means, it cannot scanf the 'df= ...'
I also noticed that I now have to include the '@' char, when before I didn't have to.
That change appeared between 3.14.8 and 3.14.11

What is the correct way to read the INP field now?
