boost c tutorial

Recently began to write a thread pool, during which I wanted to use a generic function template to make each thread perform different tasks and find the function functions in the Boost library.Boost::function is a function wrapper, or a function template, that can be used in place of different functions that have the same return type, the same parameter type, and the same number of arguments.1#include 2#include 3typedef

Boost. Asio c ++ network programming translation (21), boost. asio Network ProgrammingThe author of synchronous VS asynchronous Boost. Asio made a very amazing job: it allows you to freely choose between synchronous and asynchronous, so as to better adapt to your application. In the previous sections, we learned the frameworks of each type of application, such as

customers continue to be your customers, because the loss of an old customer, cost three times times to develop a new customer. In software design and hardware design, the biggest difference is that the software design needs to be compatible with the old version, need to maintain and upgrade, maybe this is the software can not appear on the hardware IC industry reasons. Here's a look at the example of sending the data, the following code: Boost_022.cpp:Defines the entry point for the console a

This article is a brief introduction to the very useful library functions in boost---Multiple index multi_index, whose underlying structure is the data structure used to store the map of the structure body. However, unlike the ordinary map in Stl,boost, it can specify the type of index according to the needs of the user, that is, the value of the key can vary depending on the needs. For example, now I

The SEPIC (single-ended, Primary-inductance-converter) topology is generally a good choice for voltage regulators that Mus t produce an on output voltage so falls in the middle of the input-voltage range, such as a 5V output from a 2.7 to 6V I Nput, the topology has some disadvantages, however. The efficiency of a SEPIC circuit fares worse than that of buck and boost regulators, and SEPIC designs often involve theUse of large, complex magnetic compone

Boost: to_upper_copy has two constructor types, especially the second one,Note: Use of Boost: Range.Function Format: Template Example: // The to_upper_copy overload function void test_string_upper () {STD: String str1 = "Hello world! "; // Method 1std: String str2 = boost: to_upper_copy (str1); Assert (str2 =" Hello world! "); // Method 2, the second parame

Function objects and High-Order programming (function objects and higher-order programming) boost. Bind BIND is a generalization of the standard library binder (bind1st and bind2nd. This library supports binding any behavior similar to a function, function pointer, function object, or member function pointer using a unified syntax. It also supports functional composition ). This library does not need the prerequisites required by the standard librar

1. introduction boost. the function library contains the packaging of function objects of a class family. It is similar to a callback function in a broad sense. It has the same features as function pointers but also contains a called interface. A function pointer can be called locally or used as a callback function. Boost. function can replace function pointers and provide greater flexibility. 2. use

Namespace {// strand provides serial execution to ensure thread security. The post or dispatch method will not be executed concurrently. // io_service cannot guarantee thread security.

Install the boost library and windows boost library in windows I plan to get familiar with boost within two months. Today, I tried to install the boost library on my win10 system. The following is a summary of the problems encountered: 1. Check the 1.61 version library and run bootstrap. bat in the

We all hope that we can operate arrays like operating STL containers. c ++ does not provide this. Sometimes you may choose to use vector instead, but this is not a good solution after all, after all, it is relatively safe to simulate a Dynamic Array Using Vector instead of a normal array. The overhead is too large after all. The boost: array provides this function for you.1. Such a collection has the following features:(1) No user-declared constructor

boost: noncopyable is simple and mainly used for Singleton cases. generally, to write a singleton class, you must declare the constructor of the class, value assignment function , destructor , and the copy constructor is hidden in private or protected , this is troublesome for every class. There Is A noncopyable class, as long as the singleton class directly inherits noncopyable. the basic idea of class noncopyable is to set the protected perm

of the database, and the hardware simply can not keep up with demand. Especially like today's mobile network environment, in the mobile phone there is a relatively simple, comparison of the small software, so it is impossible to do a lot of complex functions, must be in the server domain to do very strong, so as to provide strong features, such as speech recognition on the server to do. This shows that the development of the server in the software industry, become more and more important. How c

Input/output boost. Assign The assign helps to store the values of a sequence into the container. It provides a simple value assignment method by reloading the comma and parentheses operators (operators used for function calls. This library is particularly useful not only for Prototyping-style code, but also for its features, because the code generated by using this library is very readable. You can also use the list_of library to create an anonymou

Math and numerics boost. Integer This library provides a series of functions for the integer type, such as the maximum value and minimum value constant at the time of compilation [3]. The appropriate size type is given based on the required number of digits, static computing base on 2 logarithm and other functions. It also includes some Type Definitions (typedefs) of the standard header file The authors of integer are beman Dawes and daryle Walker.

Function declaration: template Example: // Find_first: [1] searches for the position where the string first appears in the input. // Find_last: [2] locate the last position of the string in the input. // Find_nth: [3] searches for the position where the string appears for the nth time (counted from 0) in the input. // Find_head: [4] Take a string that starts with n characters, equivalent to substr (0, n); // find_tail: [5] returns a string with n characters at the end of a string.

1. ConceptThe range concept is similar to the container concept in STL. An interval provides an iterator that can access elements in [first, one_past_last) of a semi-open interval, and provides information about the number of elements in the interval.1.1 PurposeThe purpose of introducing the range concept is to include many types similar to containers and simplified algorithms for these types.1.2 type usedSimilar to standard containersSTD: pair Built-in array2.
