Detailed Description

template<class driver_t>
class dx::service::driver< driver_t >

service driver interface class

This is the interface to a service driver identified by a set of matching dx::guid IDs. The driver class is a helper to create device objects and to bind the device to the driver identified by the set of matching dictionaries.

device arrival/removal is initiated by launch/conclude at driver start/end and as registry notification. Therefor manipulating the device std::deque needs to be locked.

Exceptions

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