dio_can_trigger_snapshot_c

	status.i4.v = dio_can_trigger_snapshot_c(device_indices.i4a.r,
						 can_triggers.i4a.r,
						 errors.i2a.r,
						 num_devices.i4.v)

	This routine determines whether or not a device or a list of
	devices can trigger a snapshot read.

	device_indices	device index or array of device indices
	can_triggers	returned snapshot trigger capability or array of
			returned capabilities
			(TRUE -> device can trigger a snapshot,
			 FALSE -> device cannot trigger a snapshot,
			 DIO_INVALID_DATA -> error occurred in reading data)
	errors		returned error status or array of errors
	num_devices	number of devices (default is 1)

	This function returns ACNET status values as follows:

	OK			success
	positive value		number of devices in error indicating partial
				success

	This function requires the following include files:

	cnsparam_h, diolib_h, acnet_errors_h
