.SH 説明
.\"O The

.\"O function compares the first \fIn\fP bytes of the
.\"O memory areas \fIs1\fP and \fIs2\fP.
.\"O It returns an integer less than,
.\"O equal to, or greater than zero if \fIs1\fP is found, respectively, to
.\"O be less than, to match, or be greater than \fIs2\fP.
.BR memcmp ()
関数は、メモリ領域 \fIs1\fP と\fIs2\fP の最初の \fIn\fP
バイトを比較する。
\fIs1\fP が \fIs2\fP より小さいか、同じか、あるいは大きいかによって
それぞれ、負の整数、0、正の整数を返す。
