PROLOG         top

       This manual page is part of the POSIX Programmer's Manual.  The Linux
       implementation of this interface may differ (consult the
       corresponding Linux manual page for details of Linux behavior), or
       the interface may not be implemented on Linux.

NAME         top

       wcsdup — duplicate a wide-character string

SYNOPSIS         top

       #include <wchar.h>

       wchar_t *wcsdup(const wchar_t *string);

DESCRIPTION         top

       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         top

       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         top

       The wcsdup() function shall fail if:

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

       The following sections are informative.

EXAMPLES         top

       None.

APPLICATION USAGE         top

       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         top

       None.

FUTURE DIRECTIONS         top

       None.
