wcsdup
WCSDUP(3) Linux Programmer's Manual WCSDUP(3)NAME
wcsdup - duplicate a wide-character string
SYNOPSIS
#include <wchar.h>
wchar_t *wcsdup(const wchar_t *s);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

DESCRIPTION
The wcsdup() function is the wide-character equivalent of the strdup(3) function. It allocates and returns a new wide-character string
whose initial contents is a duplicate of the wide-character string pointed to by s.
Memory for the new wide-character string is obtained with malloc(3), and should be freed with free(3).
RETURN VALUE
The wcsdup() function returns a pointer to the new wide-character string, or NULL if sufficient memory was not available.
ERRORS
ENOMEM Insufficient memory available to allocate duplicate string.
CONFORMING TO
POSIX.1-2008. This function is not specified in POSIX.1-2001, and is not widely available on other systems.
