NAME

6       wmemmove - copy wide characters in memory with overlapping areas
7

SYNOPSIS

9       #include <wchar.h>
10
11       wchar_t *wmemmove(wchar_t *ws1, const wchar_t *ws2, size_t n);

DESCRIPTION

15       The  wmemmove()  function  shall copy n wide characters from the object
16       pointed to by ws2 to the object pointed to by ws1. Copying  shall  take
17       place as if the n wide characters from the object pointed to by ws2 are
18       first copied into a temporary array of n wide characters that does  not
19       overlap the objects pointed to by ws1 or ws2, and then the n wide char‐
20       acters from the temporary array are copied into the object  pointed  to
21       by ws1.
22
23       This  function  shall  not be affected by locale and all wchar_t values
24       shall be treated identically. The null wide character and wchar_t  val‐
25       ues  not  corresponding  to  valid characters shall not be treated spe‐
26       cially.
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 wmemmove() function shall return the value of ws1.
