Thinking Asynchronously in C++

System error support in C++0x - part 5

[ part 1, part 2, part 3, part 4 ]creating your own error conditionsuser-extensibility in the <system_error> facility is not limited to error codes: error_condition permits the same customisation.why create custom error conditions?to answer this question, let's revisit the distinction between error_code and error_condition:class error_code - represents...

System error support in C++0x - part 4

[ part 1, part 2, part 3 ]creating your own error codesas i stated in part 1, one of the principles behind the <system_error> facility is user-extensibility. this means that you can use the mechanism just described to define your own error codes.in this section, i'll outline what you need to do. as a basis for a worked example, i will assume you're wri...

System error support in C++0x - part 3

[ part 1, part 2 ]enumerators as class constantsas we have seen, the <system_error> header defines enum class errc:enum class errc{ address_family_not_supported, address_in_use, ... value_too_large, wrong_protocol_type,};the enumerators of which are placeholders for error_condition constants:std::error_code ec;create_directory("/some/path", ec);if (ec ...

System error support in C++0x - part 2

[ part 1 ]error_code vs error_conditionof the 1000+ pages of c++0x draft, the casual reader is bound to notice one thing: error_code and error_condition look virtually identical! what's going on? is it a copy/paste error?it's what you do with it that countslet's review the descriptions i gave in part 1:class error_code - represents a specific error value...

Thinking Asynchronously in C++

System error support in C++0x - part 1

among the many new library features in c++0x is a little header called <system_error>. it provides a selection of utilities for managing, well, system errors. the principal components defined in the header are:class error_categoryclass error_codeclass error_conditionclass system_errorenum class errci had a hand in the design of this facility, so in thi...

Thinking Asynchronously in C++

Bind illustrated

asynchronous operations in asio all expect a function object argument, the completion handler, which they invoke when the asynchronous operation completes. the signature of the handler depends on the type of operation. for example, a handler posted using io_service::post() must have the signature:void handler();while an asynchronous wait operation expect...

Timeouts by analogy

most networking-enabled applications have to deal with timeouts. read or write operations may continue indefinitely, and programs need a way to determine when to tear down connections, resend requests, or take whatever other measures are necessary.asio includes the deadline_timer class for managing timeouts. this class aims to provide a minimal interface...
