+.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
+bcopy \- memory operations (\fBLEGACY\fP)
+.SH SYNOPSIS
+.LP
+\fB#include <strings.h>
+.br
+.sp
+void bcopy(const void *\fP\fIs1\fP\fB, void *\fP\fIs2\fP\fB, size_t\fP
+\fIn\fP\fB); \fP
+\fB

+\fP
+.SH DESCRIPTION
+.LP
+The \fIbcopy\fP() function shall copy \fIn\fP bytes from the area
+pointed to by \fIs1\fP to the area pointed to by
+\fIs2\fP.
+.LP
+The bytes are copied correctly even if the area pointed to by \fIs1\fP
+overlaps the area pointed to by \fIs2\fP.
+.SH RETURN VALUE
+.LP
+The \fIbcopy\fP() function shall not return a value.
+.SH ERRORS
+.LP
+No errors are defined.
+.LP
+\fIThe following sections are informative.\fP
+.SH EXAMPLES
+.LP
+None.
+.SH APPLICATION USAGE
+.LP
+The \fImemmove\fP() function is preferred over this function.
+.LP
+The following are approximately equivalent (note the order of the
+arguments):
+.sp
+.RS
+.nf
+
+\fBbcopy(s1,s2,n) ~= memmove(s2,s1,n)
+\fP
+.fi
+.RE
+.LP
+For maximum portability, it is recommended to replace the function
+call to \fIbcopy\fP() as follows:
+.sp
+.RS
+.nf
+
+\fB#define bcopy(b1,b2,len) (memmove((b2), (b1), (len)), (void) 0)
+\fP
+.fi
+.RE
+.SH RATIONALE
+.LP
+None.
+.SH FUTURE DIRECTIONS
+.LP
+This function may be withdrawn in a future version.
