mmeemmccppyy(_v_o_i_d _*_d_s_t, _c_o_n_s_t _v_o_i_d _*_s_r_c, _s_i_z_e___t _l_e_n)
DDEESSCCRRIIPPTTIIOONN
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 C3.1591989 (``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().
