stripos — Find position of first occurrence of a case- insensitive string int stripos ( char* haystack, char* needle, int offset ) Returns the numeric position of the first occurrence of needle in the haystack string. Note that the needle may be a string of one or more characters. If needle is not found, stripos() will return -1. The function should not make use of any C library function calls.
