Hi,
I'm analyzing volser/dumpstuff.c.
I can't understand the second part of this function:
static void
ReadString(register struct iod *iodp, register char *to, register int maxa)
{
register int c;
while (maxa--) {
if ((*to++ = iod_getc(iodp)) == 0)
break;
}
if (to[-1]) {
while ((c = iod_getc(iodp)) && c != EOF);
to[-1] = 0;
}
}
What I don't really understand, what's that to[-1] stuff there?
(Anyway: is it correct in C having array index of -1? I haven't seen such
before...)
If anybody knows the answer, please tell me.
