spbcx.h contains the following programming interfaces:

Functions

SPB_CONNECTION_PARAMETERS_INIT The SPB_CONNECTION_PARAMETERS_INIT function initializes an SPB_CONNECTION_PARAMETERS structure.
SPB_CONTROLLER_CONFIG_INIT The SPB_CONTROLLER_CONFIG_INIT function initializes an SPB_CONTROLLER_CONFIG structure.
SPB_REQUEST_PARAMETERS_INIT The SPB_REQUEST_PARAMETERS_INIT function initializes an SPB_REQUEST_PARAMETERS structure.
SPB_TRANSFER_DESCRIPTOR_INIT The SPB_TRANSFER_DESCRIPTOR_INIT function initializes an SPB_TRANSFER_DESCRIPTOR structure.
SpbControllerSetIoOtherCallback The SpbControllerSetIoOtherCallback method registers an SPB controller driver's EvtSpbControllerIoOther callback function.
SpbControllerSetRequestAttributes The SpbControllerSetRequestAttributes method sets object attributes that will be used for all SPBREQUEST objects that the SPB framework extension (SpbCx) delivers to the SPB controller driver.
SpbControllerSetTargetAttributes The SpbControllerSetTargetAttributes method sets object attributes that will be used for all SPBTARGET objects that the SPB framework extension (SpbCx) delivers to the SPB controller driver.
SpbDeviceInitConfig The SpbDeviceInitConfig method attaches the SPB framework extension (SpbCx) to the I/O-request chain for a WDFDEVICE (FDO or PDO) object that is to be created.
SpbDeviceInitialize The SpbDeviceInitialize method completes the initialization of the SPB controller driver after this driver creates the associated device object.
SpbRequestCaptureIoOtherTransferList The SpbRequestCaptureIoOtherTransferList method retrieves the SPB_TRANSFER_LIST structure in the input buffer of the custom IOCTL request.
SpbRequestComplete The SpbRequestComplete method completes an I/O request and supplies a completion status.
SpbRequestGetController The SpbRequestGetController method returns the WDFDEVICE handle to the device object for the SPB controller that the specified I/O request was sent to.
SpbRequestGetParameters The SpbRequestGetParameters method retrieves a set of SPB-specific parameter values from an I/O request.
SpbRequestGetTarget The SpbRequestGetTarget method retrieves the SPBTARGET handle from the specified I/O request.
SpbRequestGetTransferParameters The SpbRequestGetTransferParameters method retrieves the transfer parameters for an individual transfer in an I/O transfer sequence.
SpbTargetGetConnectionParameters The SpbTargetGetConnectionParameters method retrieves the connection parameters for a target device on the bus.
SpbTargetGetFileObject The SpbTargetGetFileObject method accepts, as an input parameter, an SPBTARGET handle to an open target device, and returns a WDFFILEOBJECT handle to this target.

Callback functions

EVT_SPB_CONTROLLER_LOCK An SPB controller driver's EvtSpbControllerLock event callback function locks the SPB controller for accesses of a single target device on the bus.
EVT_SPB_CONTROLLER_OTHER An SPB controller driver's EvtSpbControllerIoOther event callback function handles device I/O control requests that are not handled by other event callback functions or by the SPB framework extension (SpbCx).
EVT_SPB_CONTROLLER_READ An SPB controller driver's EvtSpbControllerIoRead event callback function reads data from the specified target device into the buffers that are supplied with the read request.
EVT_SPB_CONTROLLER_SEQUENCE An SPB controller driver's EvtSpbControllerIoSequence event callback function performs a sequence of data transfers between the specified target device and the buffers that are supplied with the sequence request.
EVT_SPB_CONTROLLER_UNLOCK An SPB controller driver's EvtSpbControllerUnlock event callback function unlocks the SPB controller, which was locked by a previous call to the EvtSpbControllerLock event callback function.
EVT_SPB_CONTROLLER_WRITE An SPB controller driver's EvtSpbControllerIoWrite event callback function writes data to the specified target device from the buffers that are supplied with the write request.
EVT_SPB_TARGET_CONNECT An SPB controller driver's EvtSpbTargetConnect event callback function opens a connection to a target device on the bus.
EVT_SPB_TARGET_DISCONNECT An SPB controller driver's EvtSpbTargetDisconnect event callback function closes a connection to a target device that was previously opened by a call to the driver's EvtSpbTargetConnect event callback function.

Structures

SPB_CONNECTION_PARAMETERS The SPB_CONNECTION_PARAMETERS structure contains the connection parameters for a target device on a simple peripheral bus.
SPB_CONTROLLER_CONFIG The SPB_CONTROLLER_CONFIG structure contains the configuration settings for an SPB controller driver.
SPB_TRANSFER_DESCRIPTOR The SPB_TRANSFER_DESCRIPTOR structure describes a single transfer in an I/O transfer sequence.

Enumerations

SPB_REQUEST_SEQUENCE_POSITION The SPB_REQUEST_SEQUENCE_POSITION enumeration indicates the position of an I/O request in the list of transfers for an I/O transfer sequence.
SPB_REQUEST_TYPE The SPB_REQUEST_TYPE enumeration specifies the type of SPB operation that a client is requesting.
