2 | FUNCTION |
---|
3 | <<wcpcpy>>---copy a wide-character string returning a pointer to its end |
---|
4 | |
---|
5 | SYNOPSIS |
---|
6 | #include <wchar.h> |
---|
7 | wchar_t *wcpcpy(wchar_t *<[s1]>, const wchar_t *<[s2]>); |
---|
8 | |
---|
9 | DESCRIPTION |
---|
10 | The <<wcpcpy>> function copies the wide-character string pointed to by |
---|
11 | <[s2]> (including the terminating null wide-character code) into the |
---|
12 | array pointed to by <[s1]>. If copying takes place between objects that |
---|
13 | overlap, the behaviour is undefined. |
---|
14 | |
---|
15 | RETURNS |
---|
16 | This function returns a pointer to the end of the destination string, |
---|
17 | thus pointing to the trailing '\0'. |
---|
18 | |
---|
19 | PORTABILITY |
---|
20 | <<wcpcpy>> is a GNU extension. |
---|
21 | |
---|
22 | No supporting OS subroutines are required. |
