Why doesn't this use strncmp?
Thanks,

I suspect that is how this code came from Mylex many years ago. Using
strncmp would indeed be a better way to clean this up. Also, further
down in the same routine:
if (FPT_scamInfo[match].state == ID_UNUSED) {
for (k = 0; k < ID_STRING_LENGTH; k++) {
FPT_scamInfo[match].id_string[k] =
p_id_string[k];
}
This should use strncpy instead. There is another similar spot further down.
Christophe, if you can send a new patch with these clean-ups, that would
be great.
Thanks,
Khalid
