io_context::strand::dispatch (1 of 2 overloads)

Request the strand to invoke the given function object.

template<
    typename Function,
    typename Allocator>
void dispatch(
    Function && f,
    const Allocator & a) const;

This function is used to ask the strand to execute the given function object on its underlying io_context. The function object will be executed inside this function if the strand is not otherwise busy and if the underlying io_context's executor's dispatch() function is also able to execute the function before returning.

Parameters

f

The function object to be called. The executor will make a copy of the handler object as required. The function signature of the function object must be:

void function();

a

An allocator that may be used by the executor to allocate the internal storage needed for function invocation.
