post (1 of 3 overloads)

Submits a completion token or function object for execution.

template<
    typename NullaryToken>
auto post(
    NullaryToken && token);

This function submits an object for execution using the object's associated executor. The function object is queued for execution, and is never called from the current thread prior to returning from post().

The use of post(), rather than defer, indicates the caller's preference that the function object be eagerly queued for execution.

Parameters

token

The completion token that will be used to produce a completion handler. The function signature of the completion handler must be:

void handler();
Return Value

This function returns async_initiate<NullaryToken, void()>(Init{}, token), where Init is a function object type defined as:

class Init
{
public:
  template <typename CompletionHandler>
    void operator()(CompletionHandler&& completion_handler) const;
};

The function call operator of Init:

Completion Signature
void()
