>From my experience, if "%[^,]" sees a ',' before it sees anything
else, it will stop trying to read and return the number of arguments
that have successfully been read.  Apparently, scanf considers it an
error if it is told to read everything but ',' but then can't read
anything. So, my suggestion is to print out what sscanf is returning.
My bet is that sscanf is returning 1.
