| _IRQL_requires_ | ( | PASSIVE_LEVEL | ) |
Sends a synchronous IOCTL to the specified device object.
- Parameters
-
[in] IoControlCode The IOCTL to send to the device. [in] DeviceObject Pointer to the device object that will handle the IOCTL. [in] InputBuffer Optional pointer to a buffer containing input data for the IOCTL. When specified, the buffer should be at least of InputBufferLength size. [in] InputBufferLength Size in bytes, of the buffer pointed by InputBuffer. [out] OutputBuffer Optional pointer to a buffer that will receive output data from the IOCTL. When specified, the buffer should be at least of OutputBufferLength size. [in] OutputBufferLength Size in bytes, of the buffer pointed by OutputBuffer. [in] FileObject Optional pointer to a file object that may be necessary for the IOCTL.
- Returns
- An NTSTATUS code indicating success or failure of this function.
- Note
- Must be called at PASSIVE_LEVEL with all APCs enabled.
Nothing is found unless the PCI bus driver publishes the properties.
The root hub name without its prefix; NULL when the PDO has no name.
Grows a private buffer to what the helper asks for.
Lets KMDF handle the IRP, then hands it back here still uncompleted.
Waits for the device machine to answer a PnP or power event; returns the PnP status.
Deletes the UCX endpoints of the disabled pipes, then the interface record.
One 4 byte value; the registry type is not checked.
Reread whenever user experience settings change; the open status is returned.
Sends a synchronous IOCTL to the specified device object.
STATUS_SUCCESS when the caller's token is an administrator's.
Sends a synchronous IOCTL to the specified device object.
Reads one value of a walk. A missing value only clears Present; FALSE means stop.
Reads up to Size bytes of a value into a zeroed buffer; the type is not checked.
Writes a REG_BINARY value into the device's usbflags subkey.
Sets or clears ExtPropertiesInstalled from ExtPropDescSemaphore in the hardware key.
