+.SH PROLOG
+This manual page is part of the POSIX Programmer's Manual.
+The Linux implementation of this interface may differ (consult
+the corresponding Linux manual page for details of Linux behavior),
+or the interface may not be implemented on Linux.

+.SH NAME
+memcmp
+\(em compare bytes in memory
+.SH SYNOPSIS
+.LP
+.nf
+#include <string.h>
+.P
+int memcmp(const void *\fIs1\fP, const void *\fIs2\fP, size_t \fIn\fP);
+.fi
+.SH DESCRIPTION
+The functionality described on this reference page is aligned with the
+ISO\ C standard. Any conflict between the requirements described here and the
+ISO\ C standard is unintentional. This volume of POSIX.1\(hy2008 defers to the ISO\ C standard.
+.P
+The
+\fImemcmp\fR()
+function shall compare the first
+.IR n
+bytes (each interpreted as
+.BR "unsigned char" )
+of the object pointed to by
+.IR s1
+to the first
+.IR n
+bytes of the object pointed to by
+.IR s2 .
+.P
+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
+.BR "unsigned char" )
+that differ in the objects being compared.
+.SH "RETURN VALUE"
+The
+\fImemcmp\fR()
+function shall return an integer greater than, equal to, or less than
+0, if the object pointed to by
+.IR s1
+is greater than, equal to, or less than the object pointed to by
+.IR s2 ,
+respectively.
+.SH ERRORS
+No errors are defined.
