    Command:

    wcsdup

    
    
    

    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
