#### NAME

> wcpcpy, wcscpy - copy a wide-character string, returning a pointer to its end

#### SYNOPSIS

> ``#include <wchar.h>
> ``

> ``[CX] wchar_t *wcpcpy(wchar_t *restrict` ws1`, const wchar_t *restrict` ws2`);``
> `
> wchar_t *wcscpy(wchar_t *restrict` ws1`, const wchar_t *restrict` ws2`);
> `

#### DESCRIPTION

> For wcscpy(): [CX] 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.1-2008 defers to the ISO C standard.

> The [CX] 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.

#### RETURN VALUE

> [CX] 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.

#### ERRORS

> No errors are defined.

The following sections are informative.

#### EXAMPLES

> None.

#### APPLICATION USAGE

#### CHANGE HISTORY

> First released in Issue 4. Derived from the MSE working draft.

#### Issue 6

> The wcscpy() prototype is updated for alignment with the ISO/IEC 9899:1999 standard.

#### Issue 7
