(See accompanying / file LICENSE_1_0.txt or copy at http://www.boost.org/LICENSE_1_0.txt) /] [section:ReadHandler Read handler requirements] A read handler must meet the requirements for a [link asio.reference.Handler handler]. A value `h` of a read handler class should work correctly in the expression `h(ec, s)`, where `ec` is an lvalue of type `const error_code` and `s` is an lvalue of type `const size_t`. [heading Examples] A free function as a read handler: void read_handler( const asio::error_code& ec, std::size_t bytes_transferred) { ... } A read handler function object: struct read_handler { ... void operator()( const asio::error_code& ec, std::size_t bytes_transferred) { ... } ... }; A lambda as a read handler: socket.async_read(... [](const asio::error_code& ec, std::size_t bytes_transferred) { ... }); A non-static class member function adapted to a read handler using `std::bind()`: void my_class::read_handler( const asio::error_code& ec, std::size_t bytes_transferred) { ... } ... socket.async_read(..., std::bind(&my_class::read_handler, this, std::placeholders::_1, std::placeholders::_2)); A non-static class member function adapted to a read handler using `boost::bind()`: void my_class::read_handler( const asio::error_code& ec, std::size_t bytes_transferred) { ... } ... socket.async_read(..., boost::bind(&my_class::read_handler, this, asio::placeholders::error, asio::placeholders::bytes_transferred)); [endsect]
