PROLOG

6       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
7       implementation of this interface may differ (consult the  corresponding

9       not be implemented on Linux.

NAME

13       wmemcpy — copy wide characters in memory
14

SYNOPSIS

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

DESCRIPTION

22       The functionality described on this reference page is aligned with  the
23       ISO C  standard.  Any  conflict between the requirements described here
24       and the ISO C standard is unintentional. This  volume  of  POSIX.1‐2008
25       defers to the ISO C standard.
26
27       The  wmemcpy()  function  shall  copy n wide characters from the object
28       pointed to by ws2 to the object pointed to by ws1.  This function shall
29       not be affected by locale and all wchar_t values shall be treated iden‐
30       tically. The null wide character and wchar_t values  not  corresponding
31       to valid characters shall not be treated specially.
32
33       If  n  is zero, the application shall ensure that ws1 and ws2 are valid
34       pointers, and the function shall copy zero wide characters.
35

RETURN VALUE

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