Send Feedback

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

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

Parameters

  • hBusAccess
    [in] Handle obtained from CreateBusAccessHandle.

  • 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.
    • For a 32-bit PC Card, you can use PCCARD_PCI_CONFIGURATION_SPACE.
    • For a 16-bit PC Card, you can use PCCARD_ATTRIBUTE_MEMORY, PCCARD_COMMON_MEMORY, PCCARD_ATTRIBUTE_MEMORY_INDIRECT, or PCCARD_COMMON_MEMORY_INDIRECT.

    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 Values

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

Requirements

OS Versions: Windows CE 5.0 and later.
Header: CEDDK.h.
