This function retrieves the reading when the
called.
Arguments
handle
value

Sample code
Code extract to get a single value reading without blocking the calling thread:
HRDLGetSingleValueAsync
short HRDLGetSingleValueAsync (
void main()
{
BOOL
short channelNo;
long
short handle;
// open and initialise the unit
// set the channel parameters
channelNo = HRDL_ANALOG_IN_CHANNEL_1;
range = HRDL_2500_MV;
singleEnded = TRUE;
bConversionFinished = FALSE;
while (true)
{
short handle,
long
short * overflow )
if a valid handle is passed and the function succeeds
if not
PollSingleValue(handle,
if(bConversionFinished == TRUE)
{
.
.
.
// do something with the value
channelNo++;
Handle returned by
Pointer to a long where the ADC value will be written
Pointer to a value that indicates when the voltage on a channel has
exceeded the upper or lower limits.
