On Windows, one can use tmpfile_s().
Do NOT use tmpfile() ('secure' or not). Due to the DOS legacy, it tries to create the file in the root directory of the current drive, which fails for C:\ under non-admin user on Vista and later. Use instead tmpnam() followed by fopen() with mode "w+bTD" (write, binary, temporary, delete on close).
