nimm lieber gleich strtok_r statt deiner "unsafen" stok/strtok lösung, falls strtok_r nicht vorhanden ist, das hier nehmen:
| C++: |
char * strtok_r (char *s, char *delim, char **lasts)
{
register char *spanp;
register int c, sc;
char *tok;
if (s == NULL && (s = *lasts) == NULL)
return (NULL);
/*
* Skip (span) leading delimiters (s += strspn(s, delim), sort of).
*/
cont:
c = *s++;
for (spanp = (char *)delim; (sc = *spanp++) != 0;) {
if (c == sc)
goto cont;
}
if (c == 0) { /* no non-delimiter characters */
*lasts = NULL;
return (NULL);
}
tok = s - 1;
/*
* Scan token (scan for delimiters: s += strcspn(s, delim), sort of).
* Note that delim must have one NUL; we stop if we see that, too.
*/
for (;;) {
c = *s++;
spanp = (char *)delim;
do {
if ((sc = *spanp++) == c) {
if (c == 0)
s = NULL;
else
s[-1] = 0;
*lasts = s;
return (tok);
}
} while (sc != 0);
}
/* NOTREACHED */
}

Auch wenn da ein goto drin ist, aber schliesslich ist das von 1988
