<p>OPENSSL_strcasecmp, OPENSSL_strncasecmp - compare two strings ignoring case</p>

|

|
|
|
||
|
|
<p>The OPENSSL_strcasecmp function performs a byte-by-byte comparison of the strings <b>s1</b> and <b>s2</b>, ignoring the case of the characters.</p>
|
||
|
|
|
||
|
|
<p>The OPENSSL_strncasecmp function is similar, except that it compares no more than <b>n</b> bytes of <b>s1</b> and <b>s2</b>.</p>
|
||
|
|
|
||
|
|
<p>In POSIX-compatible system and on Windows these functions use "C" locale for case insensitive. Otherwise the comparison is done in current locale.</p>

<h1 id="RETURN-VALUES">RETURN VALUES</h1>
|
||
|
|
|
||
|
|
<p>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.</p>

|
<p>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.</p>
