wcsdup(3)                  Library Functions Manual                  wcsdup(3)

NAME
       wcsdup - duplicate a wide-character string

LIBRARY
       Standard C library (libc, -lc)

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
       error.

ERRORS
       ENOMEM Insufficient memory available to allocate duplicate string.
