.\"O .SH DESCRIPTION
.SH 説明
.\"O The
.\"O .BR strcasecmp ()
.\"O function compares the two strings \fIs1\fP and
.\"O \fIs2\fP, ignoring the case of the characters.
.\"O It returns an integer
.\"O less than, equal to, or greater than zero if \fIs1\fP is found,
.\"O respectively, to be less than, to match, or be greater than \fIs2\fP.
.BR strcasecmp ()
関数は、二つの文字列　\fIs1\fP と \fIs2\fP を、
大文字小文字を区別せずに比較する。
\fIs1\fP が \fIs2\fP よりも小さいか、同じか、大きいかによってそれぞれ
負の整数、0、正の整数を返す。
.PP
.\"O The
.\"O .BR strncasecmp ()
.\"O function is similar, except it only compares
.\"O the first \fIn\fP characters of \fIs1\fP.
.BR strncasecmp ()
関数も同様であるが、
\fIs1\fP の最初の \fIn\fP 文字だけを比較する点だけが異なる。
.\"O .SH "RETURN VALUE"
.SH 返り値
.\"O The
.\"O .BR strcasecmp ()
.\"O and
.\"O .BR strncasecmp ()
.\"O functions return
.\"O an integer less than, equal to, or greater than zero if \fIs1\fP
.\"O (or the first \fIn\fP bytes thereof) is found, respectively, to be
.\"O less than, to match, or be greater than \fIs2\fP.
.BR strcasecmp ()
