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 copies n wide-characters from the object pointed to by ws2 to the object pointed to by ws1 . Copying takes 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 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, ws1 and ws2 must be a valid pointers, and the function copies zero wide-characters.
RETURN VALUE
The wmemmove function returns the value of
ws1 .
