FUNCTION
<<wcsdup>>---wide character string duplicate
INDEX
wcsdup
INDEX
_wcsdup_r
SYNOPSIS
#include <wchar.h>
wchar_t *wcsdup(const wchar_t *<[str]>);
#include <wchar.h>
wchar_t *_wcsdup_r(struct _reent *<[ptr]>, const wchar_t *<[str]>);
DESCRIPTION
<<wcsdup>> allocates a new wide character string using <<malloc>>,
and copies the content of the argument <[str]> into the newly
allocated string, thus making a copy of <[str]>.
RETURNS
<<wcsdup>> returns a pointer to the copy of <[str]> if enough
memory for the copy was available. Otherwise it returns NULL
and errno is set to ENOMEM.
PORTABILITY
POSIX-1.2008
