mecar_ramp_time_to_current (ul_mecarlib)

	status.i4.v = mecar_ramp_time_to_current(time.r4.v, current.r4.r,
						 idot.r4.r, ramp_data.s.r)

	This routine calculates the current and idot for a given time
	in a MECAR ramp.

	time		time in MECAR ramp in seconds
	current		returned current in amps
	idot		returned idot value
	ramp_data	MECAR ramp data (structure of type MECAR_RAMP_TABLE)

	This function returns ACNET status values as follows:

	DIO_OK			success
	DIO_GENERR		calculation failed - probably an invalid
				time value was passed

	This function requires the following include files:

	ul_mecarlib_h:mecarlib_h, acnet_errors_h
