Answer 1

You want something like memmem (that code is licensed with the GPL).

However, it should not be difficult to roll your own. Like in memmem's implementation, you need a loop that uses memchr to find the first character of your needle in the haystack, and memcmp to test each hit and see if all of your needle is there.
