Create a new handler that automatically dispatches the wrapped handler
on the io_context.
template<
typename Handler>
unspecified wrap(
Handler handler);
This function is used to create a new handler function object that, when
invoked, will automatically pass the wrapped handler to the io_context
object's dispatch function.
The handler to be wrapped. The io_context
will make a copy of the handler object as required. The function
signature of the handler must be:
void handler(A1 a1, ... An an);
A function object that, when invoked, passes the wrapped handler to the
io_context
object's dispatch function. Given a function object with the signature:
R f(A1 a1, ... An an);
If this function object is passed to the wrap function like so:
io_context.wrap(f);
then the return value is a function object with the signature
void g(A1 a1, ... An an);
that, when invoked, executes code equivalent to:
io_context.dispatch(boost::bind(f, a1, ... an));
