- strinstr(src, pat) looks for an instance of pat in src. pat is not a
- regex(3) pattern, it is a literal string which must be matched exactly.
- The result 0 if the pattern was not found else it is the start char of
- the pattern counted from the beginning of the string, where the first
- char is 1.
