Copying takes + place as if the <[n]> wide-characters from the object pointed to by + <[s]> are first copied into a temporary array of <[n]> wide-characters + that does not overlap the objects pointed to by <[d]> or <[s]>, and then + the <[n]> wide-characters from the temporary array are copied into the + object pointed to by <[d]>. + + This function is not affected by locale and all wchar_t values are + treated identically. The null wide-character and wchar_t values not + corresponding to valid characters are not treated specially. + + If <[n]> is zero, <[d]> and <[s]> must be a valid pointers, and the + function copies zero wide-characters. + +RETURNS + The <<wmemmove>> function returns the value of <[d]>. + +PORTABILITY +<<wmemmove>> is ISO/IEC 9899/AMD1:1995 (ISO C). +No supporting OS subroutines are required. +*/ + +/* $NetBSD: wmemmove.c,v 1.1 2000/12/23 23:14:37 itojun Exp $ */ + +/*- + * Copyright (c)1999 Citrus Project, + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.
