     The mmeemmccppyy() function copies _l_e_n bytes from string _s_r_c to string _d_s_t.

RREETTUURRNN VVAALLUUEESS
     The mmeemmccppyy() function returns the original value of _d_s_t.

SSTTAANNDDAARRDDSS
     The mmeemmccppyy() function conforms to ANSI C X3.159-1989 (``ANSI C '').

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