NAMEwmemcpy - copy wide characters in memory
SYNOPSIS
#include <wchar.h>
wchar_t *wmemcpy(wchar_t *restrict ws1, const wchar_t *restrict ws2,
size_t n);
DESCRIPTION
The wmemcpy() function shall copy n wide characters from the object
pointed to by ws2 to the object pointed to by ws1. This function shall
not be affected by locale and all wchar_t values shall be treated iden‐
tically. 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 wmemcpy() function shall return the value of ws1.
ERRORS
