WMEMMOVE(3P)               POSIX Programmer's Manual              WMEMMOVE(3P)

PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the  corresponding
       Linux  manual page for details of Linux behavior), or the interface may
       not be implemented on Linux.
NAME
       wmemmove - copy wide characters in memory with overlapping areas
SYNOPSIS
       #include <wchar.h>
       wchar_t *wmemmove(wchar_t *ws1, const wchar_t *ws2, size_t n);

DESCRIPTION
       The wmemmove() function shall copy n wide characters  from  the  object
       pointed  to  by ws2 to the object pointed to by ws1. Copying shall take
       place as if the n wide characters from the object pointed to by ws2 are
       first  copied into a temporary array of n wide characters that does not
       overlap the objects pointed to by ws1 or ws2, and then the n wide char-
       acters  from  the temporary array are copied into the object pointed to
       by ws1.
       This function shall not be affected by locale and  all  wchar_t  values
       shall  be treated identically. The null wide character and wchar_t val-
       ues not corresponding to valid characters shall  not  be  treated  spe-
       cially.
       If  n  is zero, the application shall ensure that ws1 and ws2 are valid
       pointers, and the function shall copy zero wide characters.
RETURN VALUE
       The wmemmove() function shall return the value of ws1.
