Boost.Asio

fundamental concepts that went into the library. Use them in your programs.

One key criterium: should not be a framework, but a toolkit. This gives you more freedom.

Challenges of asynchronous programming:

• Object lifetimes
• Thinking asynchronously
• Threads
• ?

Object lifetimes

handlers and buffers are taken by value, a copy is made. Buffers are shallow.

Arguments taken by non-const reference: caller needs to guarantee lifetime. this-pointer should outlive operation. Newby problem: providing a buffer that goes out of scope (local variable for instance).

Use shared_ptr and shared_from_this to automatically manage object lifetime.
