+ 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.
