 * Notes:
 *\li	'template' is a reserved work in C++.  If you want to complain

 *	Merriam-Webster English dictionary. (http://www.m-w.com/)
 *
 *\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)
 *	are replaced with ASCII characters until a non-existent filename
 *	is found.  If the template does not include pathname information,

 *
 *\li	isc_file_mktemplate is a good, portable way to get a template.
 *
 * 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:

 * Returns:
