Are there any case insensitive functions in C?

While some compiler’s C libraries include extensions with case insensitive versions of the standard string functions, such as GNU’s strcasestr (), the naming of such functions is not standardised even when included. One way of overcoming the lack of a standard implementation is of course to implement your own: The test code below outputs:
