selected_entry.sp.v = clocklog_recall(key.i4.v, num_files.i4.r)

	This routine returns clocklog data for specified key.  The key is
	the entry number in the circular buffer of saved files.

	key		key to search for
	num_files	returned number of files

	This function returns status values as follows:

	NULL			no clock event data found matching the key
	otherwise		pointer to selected clock event data entry
				(structure of type cl_entry_t)

	This function requires the following include files:

	cnsparam_h, ul_cbsaux_h:clockscope_h

	Related functions:

	clocklog_save, clocklog_directory, clocklog_dates, clockscope_directory,
	clockscope_save, clockscope_recall

	C/C++ usage:

	int	key;
	int	num_files;
	cl_entry_t	*selected_entry;

	selected_entry = clocklog_recall(key,&num_files);
