Имя (Name)
wcpcpy, wcscpy — copy a wide-character string, returning a
pointer to its end
Синопсис (Synopsis)
#include <wchar.h>
wchar_t *wcpcpy(wchar_t *restrict ws1, const wchar_t *restrict ws2);
wchar_t *wcscpy(wchar_t *restrict ws1, const wchar_t *restrict ws2);
Описание (Description)
For wcscpy(): 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 wcpcpy() and wcscpy() functions shall copy the wide-character
string pointed to by ws2 (including the terminating null wide-
character code) into the array pointed to by ws1.
The application shall ensure that there is room for at least
wcslen(ws2)+1 wide characters in the ws1 array, and that the ws2
and ws1 arrays do not overlap.
If copying takes place between objects that overlap, the behavior
is undefined.
Возвращаемое значение (Return value)
The wcpcpy() function shall return a pointer to the terminating
null wide-character code copied into the ws1 buffer.
The wcscpy() function shall return ws1.
No return values are reserved to indicate an error.
