A copy of the license is included in the ``GNU Free @c Documentation License'' file as part of this distribution. The @code{c-strcaseeq} module contains an optimized case-insensitive string comparison 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 functions is actually implemented as a macro: @smallexample extern int STRCASEEQ (const char *s1, const char *s2, int s20, int s21, int s22, int s23, int s24, int s25, int s26, int s27, int s28); @end smallexample @var{s2} should be a short literal ASCII string, and @var{s20}, @var{s21}, ... the individual characters of @var{s2}. For case conversion here, only ASCII characters are considered to be upper case or lower case.
