A copy of the license is included in the ``GNU Free @c Documentation License'' file as part of this distribution. The @code{c-strcasestr} module contains a case-insensitive string search function operating on single-byte character strings, that operate as if the locale encoding was ASCII. (The "C" locale on many systems has the locale encoding "ASCII".) The function is: @smallexample extern char *c_strcasestr (const char *haystack, const char *needle); @end smallexample For case conversion here, only ASCII characters are considered to be upper case or lower case. Note: The function @code{strcasestr} from @code{<string.h>} supports only unibyte locales; for multibyte locales, you need the function @code{mbscasestr}.
