Function Documentation

AllocateTask() [1/2]

template<typename Pendable , typename... Args>

Task * pw::async2::AllocateTask	(	pw::allocator::Allocator &	allocator,
		Args &&...	args
	)

Creates a Task by dynamically allocating Task memory from allocator.

Returns nullptr on allocation failure. Pendable must have a Poll<> Pend(Context&) method. allocator must outlive the resulting Task.

AllocateTask() [2/2]

template<typename Pendable >

Task * pw::async2::AllocateTask	(	pw::allocator::Allocator &	allocator,
		Pendable &&	pendable
	)

Creates a Task by dynamically allocating Task memory from allocator.

Returns nullptr on allocation failure. Pendable must have a Poll<> Pend(Context&) method. allocator must outlive the resulting Task.

EnqueueHeapFunc()

template<typename Func >

void pw::async2::EnqueueHeapFunc	(	Dispatcher &	dispatcher,
		Func &&	func
	)

Heap-allocates space for func and enqueues it to run on dispatcher.

func must be a no-argument callable that returns void.

This function requires heap allocation using new be available.
