NAME

       wcsdup — duplicate a wide-character string

SYNOPSIS

       #include <wchar.h>

       wchar_t *wcsdup(const wchar_t *string);

DESCRIPTION

       The wcsdup() function is the wide-character equivalent of the strdup() function.

       The  wcsdup() function shall return a pointer to a new wide-character string, allocated as
       if by a call to malloc(), which is the duplicate of the wide-character string string.  The
       returned  pointer  can  be  passed to free().  A null pointer is returned if the new wide-
       character string cannot be created.

RETURN VALUE

       Upon successful completion, the wcsdup() function shall return  a  pointer  to  the  newly
       allocated  wide-character  string. Otherwise, it shall return a null pointer and set errno
       to indicate the error.

ERRORS

       The wcsdup() function shall fail if:

       ENOMEM Memory large enough for the duplicate string could not be allocated.

       The following sections are informative.

EXAMPLES

       None.

APPLICATION USAGE

       For functions that allocate memory as if by malloc(), the application should release  such
       memory  when  it  is  no  longer  required by a call to free().  For wcsdup(), this is the
       return value.

RATIONALE

       None.

FUTURE DIRECTIONS

       None.
