| 2 | FUNCTION |
|---|
| 3 | <<wcscpy>>---copy a wide-character string |
|---|
| 4 | |
|---|
| 5 | SYNOPSIS |
|---|
| 6 | #include <wchar.h> |
|---|
| 7 | wchar_t *wcscpy(wchar_t *__restrict <[s1]>, |
|---|
| 8 | const wchar_t *__restrict <[s2]>); |
|---|
| 9 | |
|---|
| 10 | DESCRIPTION |
|---|
| 11 | The <<wcscpy>> function copies the wide-character string pointed to by |
|---|
| 12 | <[s2]> (including the terminating null wide-character code) into the |
|---|
| 13 | array pointed to by <[s1]>. If copying takes place between objects that |
|---|
| 14 | overlap, the behaviour is undefined. |
|---|
| 15 | |
|---|
| 16 | RETURNS |
|---|
| 17 | The <<wcscpy>> function returns <[s1]>; no return value is reserved to |
|---|
| 18 | indicate an error. |
|---|
| 19 | |
|---|
| 20 | PORTABILITY |
|---|
| 21 | <<wcscpy>> is ISO/IEC 9899/AMD1:1995 (ISO C). |
|---|
| 22 | |
|---|
