    Defines: strinstr()

    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.
