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.
NAMEwmemmove — 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 functionality described on this reference page is aligned with the
ISO C standard. Any conflict between the requirements described here
and the ISO C standard is unintentional. This volume of POSIX.1‐2008
defers to the ISO C standard.
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.
