2 FUNCTION
3 <<wmemcpy>>---copy wide characters in memory
4
5 SYNOPSIS
6 #include <wchar.h>
7 wchar_t *wmemcpy(wchar_t *__restrict <[d]>,
8 const wchar_t *__restrict <[s]>, size_t <[n]>);
9
10 DESCRIPTION
11 The <<wmemcpy>> function copies <[n]> wide characters from the object
12 pointed to by <[s]> to the object pointed to be <[d]>. This function
13 is not affected by locale and all wchar_t values are treated
14 identically. The null wide character and wchar_t values not
15 corresponding to valid characters are not treated specially.
16
17 If <[n]> is zero, <[d]> and <[s]> must be a valid pointers, and the
18 function copies zero wide characters.
19
20 RETURNS
21 The <<wmemcpy>> function returns the value of <[d]>.
22
23 PORTABILITY
24 <<wmemcpy>> is ISO/IEC 9899/AMD1:1995 (ISO C).
25
26 No supporting OS subroutines are required.
