status.i4.v = sr_snap_date_to_file_info_c(device_index.i4.v,
						  system.i4.v, date.u4.v,

	This routine returns file information for detached snapshot
	manager data files based upon the date that they were taken.

	device_index	device index of device to search for
	system		detached snapshot manager category to search for
			(a value of SRMNGR_SNAP_ALL_SYSTEMS will result in
			 a search of all systems)
	date		desired file date
			(UTC seconds since January 1, 1970)
	file_system	returned matching file system
	file_record	returned matching file record
	[options]	directory options (unused)

	This function returns status values as follows:

	OK			success
	DIO_BADARG		invalid system or device index
	DIO_MEMFAIL		dynamic memory allocation failure
	DIO_NO_SUCH		no matching entry found
	otherwise		other ACNET error occurred

	This function requires the following include files:

	cbslib_h, acnet_errors_h
