temp_buffer

- Pointer to a location where the readings are to be placed.

times_ms_buffer

- Returns the time that the first channel was converted

(optional.)

buffer_length

- Length of data buffers.

overflow

- Pointer to a variable that will be assigned a value of 1 if an

overflow occured on any of the readings copied into

measuring range of the USB TC-08.

channel

0: USBTC08_UNITS_CENTIGRADE

1: USBTC08_UNITS_FAHRENHEIT

2: USBTC08_UNITS_KELVIN

3: USBTC08_UNITS_RANKINE

Voltages are always returned in millivolts

fill_missing

- Choose whether or not to replace QNaN values with the

last known value:

0 - Use QNaNs to represent missing readings

1 - Fill missing readings with previous good reading.

Returns:

-1

- An error occurred, use
