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)):

wcsdup():
    Since glibc 2.10:
        _XOPEN_SOURCE >= 700 || _POSIX_C_SOURCE >= 200809L
    Before glibc 2.10:
        _GNU_SOURCE

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
On success, wcsdup() returns a pointer to the new wide-character string. On error, it returns -1, with errno set to indicate the cause of the error.

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.
