Include dependency graph for dx_service_message.h:

This graph shows which files directly or indirectly include this file:

Classes
struct	dx::service::clock
	dx::ioctl::service::clock's data: the client's clock event by its name, and the client's iosize More...
struct	dx::service::create<desc_t>
	dx::ioctl::service::create's data: the device's id and its desc More...
struct	dx::service::message
	the head of every message on a service connection, its data behind it: a request, its reply or the service's broadcast More...
class	dx::service::peer
	a client's connection as the service sees it - the service's counterpart of a kernel driver's client: what the client asks lands in ioctl(), its connection's end destroys it More...

Namespaces
namespace	dx
	dynax driver framework interface namespace
namespace	dx::ioctl
	IOCTLs namespace.
namespace	dx::ioctl::service
	a service's IOCTLs beside dx::ioctl's own (log, listen): what a client asks the service's driver and devices
namespace	dx::service
	service interface namespace

Functions
template<typename value_t>
value_t	dx::service::argument(const void* in, size_t size_in)
	the IOCTL's data as the type it is to carry: exactly its size
template<typename promoted_t, typename value_t= typename promoted_t::value_t>
size_t	dx::service::exchange(promoted_t& promoted, const void* in, size_t size_in, void* out, size_t size_out)
	a value served as an IOCTL, as a kernel driver serves its promoted: in the wish, out the value - either may be absent
