PREF1 unsigned long PREF2 adc100_get_times_and_values (

long HUGE * times,

unsigned short HUGE * buffer_a,

unsigned short HUGE * buffer_b,

unsigned long no_of_values);

This routine reads a block of values from the unit in the most recent

adc100_open_unit or adc100_set_unit call. It takes readings at nominal intervals

specified in the most recent adc100_set_interval call, and returns the actual times for

each reading.

successfully collected.

When collecting data from just one channel, the parameter for the other buffer can

either be set to NULL, or pointed at the same buffer.
