SetDeviceConfigurationData (Windows Embedded CE 6.0)

1/6/2010

This function sets configuration for a device on a dynamically configurable I/O bus with a published, standard interface.

Syntax

ULONG SetDeviceConfigurationData (
  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.

• 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 where the caller-supplied configuration values begin. 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
  [in] Pointer to a caller-supplied buffer for configuration information.

Return Value

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