It copies the wide-character string pointed to by .IR src , including the terminating null wide character (L\[aq]\e0\[aq]), to the array pointed to by .IR dest . .P The strings may not overlap. .P The programmer must ensure that there is room for at least .I wcslen(src)+1 wide characters at .IR dest . .SH RETURN VALUE .BR wcpcpy () returns a pointer to the end of the wide-character string .IR dest , that is, a pointer to the terminating null wide character. .SH ATTRIBUTES For an explanation of the terms used in this section, see .BR attributes (7). .TS allbox; lbx lb lb l l l.
