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.
