Syntax

typedef struct _PCI_RSRC {
  DWORD Bus;
  DWORD Device;
  DWORD Function;
  DWORD Offset;
  DWORD Base;
  DWORD Size;
  BOOL Bridge;
  DWORD SecBus;
  BOOL Placed;
  PPCI_CFG_INFO ConfigInfo;
  struct _PCI_RSRC* Next;
  struct _PCI_RSRC* Prev;
} PCI_RSRC, *PPCI_RSRC;

Members

  PCI device bus number.

• Device
  PCI device number.

• Function
  PCI function number.

• Offset

• Placed
  TRUE if the device was previously allocated resources and active.

• ConfigInfo
  Information about the configuration routine's DLL and entry point.
