Two thoughts here:
If there should only be the occasional "incomplete" line, then you could
start by using sscanf, and then fall back to a more detailed parser.
i.e. something like:
if ( sscanf(line, "%ld,%ld,%ld",
&record[i].a,&record[i].b,&record[i].c) != 3 )
{
my_robust_parser( line, &record[i] );
}
If a significant proportion of the lines would be affected,
you could have an external process that took the raw
data file, and pre-processed it to insert the missing 0s.
(Either tweaking the code that produces this file
in the first place, or some intermediate process)
Or that process could convert from text-based CSV,
to a binary data file.
The point here is that the "slow" processing would be
taken out of the time-critical portion - i.e. the agent's
processing of an incoming request.
That's assuming that this is the cause of the problem,
of course. As I said yesterday, you probably need
to do some timing tests to check that.
