OS proxy device interface class.

This is the OS proxy device interface class. This class is used for a platform independent way of accessing kernel/driverkit devices. The device class uses the driver interface helper class to construct the device object and to bind the device to the driver identified by the io_service.

example:

try() { // guard the block
    // choose a driver
    dx::driver<>driver (match);
 
    // enumerate devices
    std::cout<< driver.size()<< " device(s) found:"<< std::endl;
 
    // go thru all devices; you have to lock the driver if this multi-threaded
    for (auto device: driver){
        // return an int32_t from an IOCTL served by the driver
        int32_t my_data= device.ioctl<int32_t>(kMyIoctl);
    }
} cd_catchall()

Exceptions

In	case of an error returned by the underlaying API the device class throws a dx::exception.

hide_if_scalar_or_ptr

template<typename type_t >

using dx::proxy::hide_if_scalar_or_ptr = std::enable_if<!(std::is_scalar_v<type_t> || std::is_pointer_v<type_t>), type_t>::type
