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

inline

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
