Parameter Type Description
handle DaqHandleT Handle to the device from which
deviceType DaqDacDeviceType Specifies the DAC type
chan DWORD
Specifies the DAC channel
fileName LPSTR String representing the path and
filename of the disk file to be output

however, disk memory limitations may apply. If set to 0, will read all cylces from the
file
offsetBytes:
the number of bytes to skip at the beginning of the file range from 0 to 4,294,967,295;
however, disk memory limitations may apply
offsetUpdateCycles:
the number of update cycles to skip at the beginning of the file range from 0 to
4,294,967,295, however, disk memory limitations may apply
