5.48 wcsdup—wide character string duplicate

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.
