io_context::basic_executor_type::dispatch

Request the io_context to invoke the given function object.

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

This function is used to ask the io_context to execute the given function object. If the current thread is running the io_context, dispatch() executes the function before returning. Otherwise, the function will be scheduled to run on the io_context.

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.
