Ceddk.dll Bus Access Functions (Compact 2013)

3/26/2014

Device Manager provides parent bus driver handles in the Active registry key. This enables subordinate drivers to access these bus functions. A set of functions can be created in Ceddk.dll to help subordinate drivers access its bus. The following table shows the functions that are provided for drivers to access the Ceddk.dll bus driver.

Function	Description
BusChildIoControl	This function sends an I/O control code to the bus driver that is related to the caller driver.
BusIoControl	This function executes the CEDDK Dynamic-Link Library Bus Access IOCTLs.
BusTransBusAddrToStatic	This function translates a bus address to a system address. Then, it creates a static, process independent, virtual address mapping for that address.
BusTransBusAddrToVirtual	This function translates a bus address to a virtual system address.
CalibrateStallCounter	This function calibrates the delay interval for StallExecution.
CloseBusAccessHandle	This function closes the handle that CreateBusAccessHandle allocated.
CreateBusAccessHandle	This function creates a handle that can be used for accessing a bus.
GetBusNamePrefix	This function returns the bus prefix name.
GetChildDeviceRemoveState	This function polls the hardware to determine whether it has been removed.
GetDeviceConfigurationData	This function retrieves configuration data from a device's configuration address space.
GetDevicePowerState	This function requests that the bus driver return the current power state of the device.
GetParentDeviceInfo	This function retrieves the device information of the parent bus driver.
HalGetBusData	This function retrieves configuration information about a specified slot or address on an I/O bus.
HalGetBusDataByOffset	This function retrieves information, starting at the offset, about a slot or address on an I/O bus.
HalSetBusData	This function sets bus-configuration data for a slot or address on a bus.
HalSetBusDataByOffset	This function sets bus-configuration data for a device on a dynamically configurable I/O bus with a published, standard interface.
HalTranslateBusAddress	This function translates a physical bus address to a physical system address.
SetDeviceConfigurationData	This function sets configuration data in a device's configuration address space.
SetDevicePowerState	This function requests that the bus driver set this device to the power state specified by PowerState.
StallExecution	This function stalls the caller on the current processor for a given interval.
TranslateBusAddr	This function translates a physical bus address to a physical system address.
TranslateSystemAddr	This function translates a physical system address to a physical bus address.
