Does anyone know what the string function strnstr does (not strstr), or if it even exists? I can't find anything about it on the Web or in print. I was told (by another programmer) to use it for a program that compares two strings (case insensitive -- which is where the strnstr is suppose to come in handy-- supposedly?). However, this programmer did not explain what strnstr does exactly! A basic definition would be nice to know and a code sample would be great!
