NAME
     bcopy -- copy byte string

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <strings.h>

     void
     bcopy(const void *src, void *dst, size_t len);

DESCRIPTION
     The bcopy() function copies len bytes from string src to string dst.  The
     two strings may overlap.  If len is zero, no bytes are copied.

HISTORY
     A bcopy() function appeared in 4.2BSD.  Its prototype existed previously
     in <string.h> before it was moved to <strings.h> for IEEE Std 1003.1-2001
     (``POSIX.1'') compliance.

     bcopy() was deprecated in IEEE Std 1003.1-2001 (``POSIX.1'') and removed
     in IEEE Std 1003.1-2008 (``POSIX.1'').
