Suppose you want to check whether there are any web links in a string, you could do:

Code:

---

const char *str = "abcdefghijklmnop http://foo.bar qrstvuwxyz", *sp;

if ((sp = strstr(str, "http://"))) handle_link(sp);

---

In this case a pointer to the substring, "http://foo.bar qrstvuwxyz" will be stored in sp. The best way to understand how strstr works would be to implement it yourself, although I'd suggest starting with strchr first.
