7.4 `wmemmove'--copy wide characters in memory with overlapping areas
SYNOPSIS
#include <wchar.h>
wchar_t *wmemmove(wchar_t *D, const wchar_t *S, size_t N);
DESCRIPTION
The `wmemmove' function copies N wide characters from the object
pointed to by S to the object pointed to by D. Copying takes place as
if the N wide characters from the object pointed to by S are first
copied into a temporary array of N wide characters that does not over‐
lap the objects pointed to by D or S, and then the N wide characters
from the temporary array are copied into the object pointed to by D.
This function is not affected by locale and all wchar_t values are
treated identically. The null wide character and wchar_t values not
corresponding to valid characters are not treated specially.
If N is zero, D and S must be a valid pointers, and the function
copies zero wide characters.
RETURNS
The `wmemmove' function returns the value of D.
PORTABILITY
