@mindex c-strcaseeq
|
|
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.
