post_ack_agent

post_ack_agent is the consumer class of post-ack. It can asynchronously poll for a value produced by the observed post_ack_mechanism.

Prototype

template <typename T>
struct post_ack_agent {
	void attach(post_ack_mechanism<T> *mech); // (1)

	void detach(); // (2)

	sender poll(cancellation_token ct = {}); // (3)
};

1. Attach the agent (consumer) to a mechanism (producer).
2. Detach the agent from the mechanism.
3. Asynchronously poll for a value.

Requirements

T is moveable.

Arguments

• mech - the mechanism to attach to.
• ct - the cancellation token to use.

Return values

1. This method doesn't return any value.
2. This method doesn't return any value.
