active
A pointer to the transfer-state flags in the form of a bit mask
retCount
A pointer to the total number of ADC scans acquired (or available) in the current transfer

Used With
All devices
daqAdcTransferGetStat
allows you to retrieve the current state of an ADC acquisition
transfer.
The
active
parameter will indicate the current state of the transfer in the form of a bit mask. Refer
to the ADC Acquisition/Transfer Active Flag Definitions (in the ADC Miscellaneous Definitions
table) for valid bit-mask states.
The
retCount
parameter will return the total number of scans acquired in the current transfer if
the transfer is in user-allocated buffer mode or will return the total number of unread scans in the
acquisition buffer if the transfer is in driver-allocated buffer mode. Refer to the
daqAdcTransferSetBuffer
function for more information on buffer allocation modes.
The transfer state and return count values will continue to be updated until any of the following
occurs:
•
the transfer count is satisfied
•
the transfer is stopped (
daqAdcStopTransfer
)
•
the acquisition is disarmed (
daqDisarm
)
