Classes
class	cuda::event_t
	Wrapper class for a CUDA event. More...

Namespaces
	cuda
	Definitions and functionality wrapping CUDA APIs.
	cuda::event
	CUDA timing functionality, via events and their related code (not including the event wrapper type event_t itself)

Typedefs
using	cuda::event::duration_t = ::std::chrono::duration< float, ::std::milli >
	The type used by the CUDA Runtime API to represent the time difference between pairs of events.

Functions
event_t	cuda::event::wrap (device::id_t device_id, context::handle_t context_handle, handle_t event_handle, bool take_ownership=false, bool hold_pc_refcount_unit=false) noexcept
	Wrap an existing CUDA event in a event_t instance. More...
::std::string	cuda::event::identify (const event_t &event)
void	cuda::wait (const event_t &event)
	Have the calling thread wait - either busy-waiting or blocking - and return only after this event has occurred (see event_t::has_occurred() More...
duration_t	cuda::event::time_elapsed_between (const event_t &start, const event_t &end)
	Determine (inaccurately) the elapsed time between two events. More...
duration_t	cuda::event::time_elapsed_between (const ::std::pair< const event_t &, const event_t &> &event_pair)
event_t	cuda::event::create (const device_t &device, bool uses_blocking_sync=sync_by_busy_waiting, bool records_timing=do_record_timings, bool interprocess=not_interprocess)
	creates a new event on (the primary execution context of) a device. More...
event_t	cuda::event::create (const context_t &context, bool uses_blocking_sync=sync_by_busy_waiting, bool records_timing=do_record_timings, bool interprocess=not_interprocess)
	creates a new event. More...
void	cuda::synchronize (const event_t &event)
