IOCTL_USBIO_GET_STATUS
The IOCTL_USBIO_GET_STATUS operation requests status for a
specific recipient.
lpInBuffer Pointer to a buffer that contains an USBIO_STATUS_REQUEST
(page 189) data structure. This data structure has to be filled completely
by the caller.
nInBufferSize Specifies the size, in bytes, of the buffer pointed to by lpInBuffer,
which has to be sizeof(USBIO_STATUS_REQUEST) for this operation.
lpOutBuffer Pointer to a buffer that will receive an
USBIO_STATUS_REQUEST_DATA (page 190) data structure.
nOutBufferSize Specifies the size, in bytes, of the buffer pointed to by lpOutBuffer,
which has to be at least sizeof(USBIO_STATUS_REQUEST_DATA) for
this operation.
Comments The GET_STATUS request appears on the bus with the parameters
specified in the USBIO_STATUS_REQUEST (page 189) structure. The
function returns the structure USBIO_STATUS_REQUEST_DATA
(page 190) which contains two bytes of data.
