Classes
class	dxd::__atomic_pointer<type_t *>
class	dxd::__atomic_scalar<4, type_t>
	32bit atomic operations More...
class	dxd::__atomic_scalar<8, type_t>
	64bit atomic operations More...
class	dxd::event<dx::kernel>
	kernel event: auto reset, as a WDM synchronization event More...
class	dxd::event<dx::user>
	kernel representation of user space event More...
class	dxd::lock<lock_t>
class	dxd::mutex
	mutex More...
class	dxd::process
	a process: launch() on a queue of its own, the event signalled on its way out More...
class	dxd::spinlock
	a dext runs at no interrupt level: what the kernel platforms take a spinlock for is a mutex here More...

Namespaces
namespace	dxd
	dynax driver framework kernel namespace

Enumerations
enum	dxd::scale : int64_t {   dxd::nsec = 1ll , dxd::usec = 1000ll , dxd::msec = usec* 1000ll , dxd::sec = msec* 1000ll ,   dxd::nsec = 1ll , dxd::usec = 1000ll , dxd::msec = usec* 1000ll , dxd::sec = msec* 1000ll }
	the factors a kernel timestamp is scaled by - the system's unit is 100 ns, so nsec is no unit of its own here More...

Functions
void	dxd::delay(int64_t time)
	DriverKit: spin the calling thread; a dext has no thread of its own to put to sleep.
unsigned int	dxd::prio()
	the level the calling code runs at: a dext runs at none, its queues serialize instead
os_result	dxd::random(void* buffer, size_t size)
	DriverKit: bytes of the kernel's cryptographic random generator.
int64_t	dxd::time()
	DriverKit: uptime in ns - the clock IOTimerDispatchSource::WakeAtTime(kIOTimerClockUptimeRaw) takes its deadlines in.
int64_t	dxd::time(int64_t timestamp, scalescale scalescale)
	a timestamp's span in the given unit: the timestamps are ns already
int64_t	dxd::timestamp()
	WDK: high precision timestamp.
int64_t	dxd::timestamp_offset(int64_t time, scalescale scalescale=usec)
	WDK: time span to timestamp span converter.
