NAME

12       wmemmove - copy wide characters in memory with overlapping areas
13

SYNOPSIS

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

DESCRIPTION

21       The wmemmove() function shall copy n wide characters  from  the  object
22       pointed  to  by ws2 to the object pointed to by ws1. Copying shall take
23       place as if the n wide characters from the object pointed to by ws2 are
24       first  copied into a temporary array of n wide characters that does not
25       overlap the objects pointed to by ws1 or ws2, and then the n wide char‐
26       acters  from  the temporary array are copied into the object pointed to
27       by ws1.
28
29       This function shall not be affected by locale and  all  wchar_t  values
30       shall  be treated identically. The null wide character and wchar_t val‐
31       ues not corresponding to valid characters shall  not  be  treated  spe‐
32       cially.
33
34       If  n  is zero, the application shall ensure that ws1 and ws2 are valid
35       pointers, and the function shall copy zero wide characters.
36

RETURN VALUE

38       The wmemmove() function shall return the value of ws1.
