 *
 *\li	This function works by using the template to generate file names.
 *	The template must be a writable string, as it is modified in place.
 *	Trailing X characters in the file name (full file name on Unix,
 *	basename on Win32 -- eg, tmp-XXXXXX vs XXXXXX.tmp, respectively)

 * Requires:
 *\li	'fp' is non-NULL and '*fp' is NULL.

 *\li	'template' is non-NULL, and of a form suitable for use by
 *	the system as described above.
 *
 * Ensures:

 *
 *\li	If result is not #ISC_R_SUCCESS:
