[in, optional] PVOID InputBuffer,
[in] ULONG InputBufferLength,
[out, optional] PVOID OutputBuffer,
[in] ULONG OutputBufferLength,
[in] PULONG_PTR IosbInformation
);
Parameters

[out, optional] OutputBuffer
An optional caller-supplied output buffer for returned data.
[in] OutputBufferLength
The length, in bytes, of the output data buffer at OutputBuffer.
[in] IosbInformation
