     MMeemmccppyy copies _l_e_n bytes from string _s_r_c to string _d_s_t and
     returns the original value of _d_s_t.

SSTTAANNDDAARRDDSS
     _M_e_m_c_p_y conforms to ANSI X3.159-1989 (``ANSI C'').

BBUUGGSS
     In this implementation mmeemmccppyy is implemented using _b_c_o_p_y(3),
     and therefore the strings may overlap.  On other systems,
     copying overlapping strings may produce surprises.  A
     simpler solution is to not use _m_e_m_c_p_y.
