Accessing Function 0 and Function 1 PCI space

NTDEV
1

Hi All,

In WDM driver, how we can get the PCI function 0 registers and PCI
function 1 registers. [ same like pci_resource_start and pci_resource_len
in linux hotswap batch].

I want to access and configure the device using these registers.

Thanks,
Sundar

Each PCI function has a device object of its own, so, you cannot
access the function which is not yours.
