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 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 IEEE Std 1003.1-2001 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 characters 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 values not corresponding to valid characters shall not be treated specially.

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.
