[Boost-users] Can I call async_write twice in a row?

Is this legal? I think I understood in the documentation that it
isn't, but I'm not
sure if it means this:

void func() {

     async_write(....);
     async_write(...);
}

So, should I do this ALWAYS?

void func() {
    async_write(..., another_func);
}

void another_func(const boost::system::error_code & ec,
                           std::size_t bytes) {
    async_write(...);

}

Thanks in advance.
