+.SH NAME
+memcmp \- compare bytes in memory
+.SH SYNOPSIS
+.LP
+\fB#include <string.h>
+.br
+.sp
+int memcmp(const void *\fP\fIs1\fP\fB, const void *\fP\fIs2\fP\fB,
+size_t\fP \fIn\fP\fB);
+.br
+\fP
+.SH DESCRIPTION
+.LP
+The \fImemcmp\fP() function shall compare the first \fIn\fP bytes
+(each interpreted as \fBunsigned char\fP) of the object
+pointed to by \fIs1\fP to the first \fIn\fP bytes of the object pointed
+to by \fIs2\fP.
+.LP
+The sign of a non-zero return value shall be determined by the sign
+of the difference between the values of the first pair of
+bytes (both interpreted as type \fBunsigned char\fP) that differ in
+the objects being compared.
+.SH RETURN VALUE
+.LP
+The \fImemcmp\fP() function shall return an integer greater than,
+equal to, or less than 0, if the object pointed to by
+\fIs1\fP is greater than, equal to, or less than the object pointed
+to by \fIs2\fP, respectively.
+.SH ERRORS
+.LP
+No errors are defined.
