How do I do DMA configuration for pci dio 32hs in VC++

[S_A_N_D_Y]

I have to configure the pci dio 32hs to do a DMA 32 bit transfer at 4Mhz. However , I've no idea how to configure the MITE register and DMA Controller to use the bus master DMA.

The NI-DAQ function call Set_DAQ_Device_Info changes the data transfer mode (interrupts and DMA) for certain classes of data acquisition operations (including buffered transfer for the PCI-DIO-32HS). Use the NI-DAQ Function Reference Manual (linked below) as a reference.
