Function Documentation

◆ _IRQL_requires_()

_Must_inspect_result_ _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.
