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:
             _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 NULL, with  errno  set  to  indicate  the
     cause of the error.

ERRORS

     ENOMEM Insufficient memory available to allocate duplicate string.
