NAME

12       wmemcpy - copy wide characters in memory
13

SYNOPSIS

15       #include <wchar.h>
16
17       wchar_t *wmemcpy(wchar_t *restrict ws1, const wchar_t *restrict ws2,
18              size_t n);

DESCRIPTION

22       The wmemcpy() function shall copy n wide  characters  from  the  object
23       pointed  to by ws2 to the object pointed to by ws1. This function shall
24       not be affected by locale and all wchar_t values shall be treated iden‐
25       tically.  The  null wide character and wchar_t values not corresponding
26       to valid characters shall not be treated specially.
27
28       If n is zero, the application shall ensure that ws1 and ws2  are  valid
29       pointers, and the function shall copy zero wide characters.
30

RETURN VALUE

32       The wmemcpy() function shall return the value of ws1.
