This article mainly introduces function objects, which may be called "high-order functions. It actually refers to a class of functions that can be passed into other functions or returned from other functions. In C ++, high-order functions are implemented as function objects. This article will introduce several boost C ++ libraries used to process function objects. Among them, boost. BIND can replace the fam

Hello, everyone, I'm an asynchronous way.
Unlike sync, I never take the time to wait for those turtle-speed IO operations, I just tell the system what to do, and then I can do something else. If the system completes the operation, the system will notify me by the callback object I gave it before.In the ASIO library, a function or method name in the asynchronous way has a "async_" prefix in front of it,
1. What is boost?The boost library is a portable C ++ library that provides source code. It covers a wide range of fields, from the mathematical Library to the smart pointer library, from the template meta programming library to the pre-processor library, from the thread to the lambda expression.TenBoost libraries are already encoded in the C ++ Standards Committee's library technical report (tr1) and will
to carefully construct applications to support such concurrency. Multi-threaded programming knowledge has become increasingly important in the multi-core system era.
This chapter introduces the C ++ boost library boost. Thread, which can develop multi-threaded applications independent of the platform.

The boost library is a portable, source-sourced C + + library that is backed up as a standard library and is one of the engines of the C + + standardization process. The Boost library was launched by the C + + Standards Committee Library team, some of which are expected to be the next generation of C + + standard library content. In the C + + community is very influential, is the absolute "quasi" standard l

Summary of the usage of auto_ptr, shared_ptr, weak_ptr and Scoped_ptr
Smart pointers, associated with reference counting
Auto_ptr: Mainly for the exception security design, in the program normal exit or abnormal termination, the class will invoke the destructor, the release of resources.
Replication \ Assignment is a corrupted operation, so you cannot bind to an array or variable pointer, and you cannot store a Auto_ptr object in a container.
