Hi, I got benifited a lot from this forum.Can you please have a look at my requirement and assist me in the same. 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. Thanks in Advance sri.
