IOCTL_USBIO_GET_INTERFACE
The IOCTL_USBIO_GET_INTERFACE operation returns the current
alternate setting of a specific interface.
lpInBuffer Pointer to a buffer that contains an USBIO_GET_INTERFACE
(page 192) 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_GET_INTERFACE) for this operation.
lpOutBuffer Pointer to a buffer that will receive an
USBIO_GET_INTERFACE_DATA (page 193) data structure.
nOutBufferSize Specifies the size, in bytes, of the buffer pointed to by lpOutBuffer,
which has to be at least sizeof(USBIO_GET_INTERFACE_DATA) for
this operation.
Comments A GET_INTERFACE request appears on the bus. The structure
USBIO_GET_INTERFACE_DATA (page 193) returns the current
alternate setting of the interface specified in USBIO_GET_INTERFACE.
