++ int OPENSSL_strncasecmp(const char *s1, const char *s2, size_t n); ++ ++=head1 DESCRIPTION ++ ++The OPENSSL_strcasecmp function performs a byte-by-byte comparison of the strings ++B and B, ignoring the case of the characters. ++ ++The OPENSSL_strncasecmp function is similar, except that it compares no more than ++B bytes of B and B. ++ ++In POSIX-compatible system and on Windows these functions use "C" locale for ++case insensitive. Otherwise the comparison is done in current locale. ++ ++=head1 RETURN VALUES ++ ++Both functions return an integer less than, equal to, or greater than zero if ++s1 is found, respectively, to be less than, to match, or be greater than s2. ++ ++=head1 NOTES ++ ++OpenSSL extensively uses case insensitive comparison of ASCII strings. Though ++OpenSSL itself is locale-agnostic, the applications using OpenSSL libraries may ++unpredictably suffer when they use localization (e.g. Turkish locale is ++well-known with a specific I/i cases). These functions use C locale for string ++comparison. ++ ++=head1 COPYRIGHT ++ ++Copyright 2022 The OpenSSL Project Authors.
