Имя (Name)
wmemcpy — copy wide characters in memory
Синопсис (Synopsis)
#include <wchar.h>
wchar_t *wmemcpy(wchar_t *restrict ws1, const wchar_t *restrict ws2,
size_t n);
Описание (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.1‐2017 defers to the ISO C standard.
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 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.
Возвращаемое значение (Return value)
The wmemcpy() function shall return the value of ws1.
