/* Generate a unique temporary file name from XTEMPLATE.
   The last six characters of XTEMPLATE must be "XXXXXX";
   they are replaced with a string that makes the file name unique.
   Then open the file and return a fd.

   If you are creating temporary files which will later be removed,
   consider using the clean-temp module, which avoids several pitfalls
   of using mkstemp directly. */
