  • [アーティクル]

3/26/2014

This function retrieves configuration data, starting at the offset, about a slot or address on an I/O bus.

Syntax

ULONG GetDeviceConfigurationData (
  HANDLE hBusAccess,
  DWORD dwSpace,
  DWORD BusNumber,
  DWORD SlotNumber,
  DWORD dwOffset,
  DWORD dwLength,
  PVOID pBuffer
);

Parameters

  • dwSpace
    [in] Configuration address space from which to get information. The following list shows the address spaces you can specify:

    • For a PCI bus, you can use PCI_WHICHSPACE_CONFIG or PCI_WHICHSPACE_ROM.

    These are defined in %_WINCEROOT%\Public\Common\DDK\Inc\Cebuscfg.h.

  • BusNumber
    [in] Zero-based and system-assigned bus number for the device, used with InterfaceType to identify the bus for systems with more than one bus of the same type.
  • SlotNumber
    [in] Logical slot number or location of the device. This value is the slot and function numbers combined.
  • dwOffset
    [in] Byte offset in the PCI_COMMON_CONFIG structure for which the requested information should be returned. Callers can use the system-defined constant PCI_COMMON_HDR_LENGTH to specify the device-specific area of PCI_COMMON_CONFIG.
  • dwLength
    [in] Maximum number of bytes in pBuffer.
  • pBuffer
    [out] Pointer to a buffer to receive configuration information.

Return Value

Returns the number of bytes of data it received in the specified buffer.
