Detailed Description

a hub as its driver reports it, usbview's view: per port the device, its speed and the pipes it holds open - the periodic load the host carries below it, the full and low speed one through the hub's transaction translator(s)

Here is the caller graph for this function:

ictl() [1/2]

template<typename rx_t>

rx_t dx::file::ictl ( unsigned int ioctl ) const

inlineinherited

Windows: member ioctl.

this member retreives data from the device by providing an IOCTL code. the template argument defines the type of data to be retreived. this member is intended as a convinient way to retreive only small amounts of data since there is an intermediate stack copy involved in returning the data.

the underlaying windows API is DeviceIoControl(). for detailed information see http://msdn.microsoft.com/en-us/library/aa363216(VS.85).aspx

Exceptions

n/a	microsoft does not give information about what possible errors values are provided by its OS other than
ERROR_INSUFFICIENT_BUFFER	if the output buffer is too small to receive any data
