NAME

       bcopy - copy byte sequence

LIBRARY

       Standard C library (libc, -lc)

SYNOPSIS

       #include <strings.h>

       [[deprecated]] void bcopy(const void src[.n], void dest[.n], size_t n);

HISTORY

       4.3BSD.

       Marked as LEGACY in POSIX.1-2001: use memcpy(3) or memmove(3) in
       new programs.  Note that the first two arguments are interchanged
       for memcpy(3) and memmove(3).  POSIX.1-2008 removes the
       specification of bcopy().
