since when has it changed practically every release? :P

word[(p-sentence)] = '\0';
}
would do the trick.. :) it has always been my interpretation that
SrtNCopy() copies n chars, unless, the source string is shorter
in which it'll copy the length of the source string only. maybe
i missed something with new versions of the os as they came out :P
to avoid any confusion, one could also do a MemSet() on the
word string prior to doing any of this :P thats pretty much
standard programming practice for me.. allocate buffer - memset
to 0 - use it - free it. :P same goes for variables.. initialize
to 0 (or default) prior to use..
