Parameter Summary
Parameter Type Description
handle DaqHandleT Handle to the device from which the current scan configuration will be
retrieved
channels PDWORD A pointer to an array which holds up to 512 channel numbers, or 0 if the
channel information is not desired
gains DaqAdcGain A pointer to an array which holds up to 512 gain values, or 0 if the
channel gain information is not desired
flags PDWORD A pointer to channel configuration flags in the form of a bit mask
chanCount PDWORD
A pointer to a variable which will hold the number of values returned in
the channels and gains arrays
Parameter Values
handle: obtained from the daqOpen parameter
channels: must be a valid pointer to an array which can hold up to chanCount channel numbers
(4 bytes/channel); valid values for channel numbers range from 0 to 512
gains: must be a valid pointer to an array which can hold up to chanCount gain definitions
(4 bytes/gain); see ADC Gain Definition table for gains valules
flags: must be a valid pointer to an array which can hold up to chanCount flag configurations
(4 bytes/flag); see ADC Flag Definition table for flags values
chanCount: defined by channel configuration; see daqAdcSetScan for details
Returns
DerrNoError No error
