NAME

6       wcsdup - duplicate a wide-character string

SYNOPSIS

10
11       wchar_t *wcsdup(const wchar_t *s);

15       wcsdup():
16           Since glibc 2.10:
17               _POSIX_C_SOURCE >= 200809L
18           Before glibc 2.10:

DESCRIPTION

22       The wcsdup() function is the wide-character equivalent of the strdup(3)
23       function.  It allocates and returns a new wide-character  string  whose
24       initial contents is a duplicate of the wide-character string pointed to
25       by s.
26
27       Memory for the new wide-character string is  obtained  with  malloc(3),
28       and should be freed with free(3).
29

RETURN VALUE

31       On  success,  wcsdup()  returns  a  pointer  to  the new wide-character
32       string.  On error, it returns NULL, with  errno  set  to  indicate  the
33       cause of the error.
34

ERRORS

36       ENOMEM Insufficient memory available to allocate duplicate string.
