WCSDUP(3)                           Linux Programmer's Manual                           WCSDUP(3)



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.
