NAME         top

       wcsdup - duplicate a wide-character string

SYNOPSIS         top

       #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         top

       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         top

       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         top

       ENOMEM Insufficient memory available to allocate duplicate
              string.
