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.
