1. Problems encountered in encapsulation Encapsulate the pthread thread as an abstract class, so that when users use the thread, they simply inherit the abstract class and implement the appropriate interface. The benefit of this is that the user can

Searched a circle of answers, basically is the start of the thread when the pass through the this pointer, the thread function of the internal and then the strong turn of the solution. May seem a little awkward. The compiler does not allow casts,

In general, a function can return a local variable. The scope of a local variable is only within the function, and after the function returns, the memory of the local variable has been freed. Therefore, if the function returns the value of a local

At the end of the fourth chapter, add a few things about inline (inline) functions:Inline function parameters with side effects, or a single expression to do multiple calls, or inline function in a number of local variables, will produce a temporary

Based on DEBIAN-40R0 (kernel 2.6.18), this article describes how to build Linux C's BASIC programming development environment in a standard system. A complete development environment consists of four parts: standard C Library, header file, tool

When I use the Pt-table-sync command--print or--execute, the following error is reported: [root@pc ~]# pt-table-sync--replicate=ccda.checksums--tables=pending_0--charset=utf8 system@123 h=192.168.1.202 u=root,p=system@123--port 3307--print

The core idea is to call the WINAPI The Getextendedtcptable method to get information about all active TCP connections, including process IDs, is mainly implemented as follows: TcpConnectionTableHelper.cs: Using System; Using

Recently, Json-rpc more interested in, the idea is simple, and see a lot of different languages to achieve. On the GitHub Hmngomes Json-rpc-c (implemented is server-side, based on TCP flow), dapper, provides a good framework, the code is very clear,

This example is used to detect the normal communication between the host and the Ping class. Delay how many milliseconds, etc... The complete code is as follows: Introduction of namespaces: Using System.Net.NetworkInformation; Complete

As a result of the project needs, the use of multithreaded solutions, where the main thread is responsible for interface processing (such as display data, and user interaction, etc.), child thread is responsible for reading and writing the serial

We know that after the DSP starts, the system will enter the reset interrupt, at this time the Reset interrupt service function is c_init00, this function is used to establish the C environment, to enter the main () function for system

Hello everyone! I am small, and meet again Ah, there is a saying "together is the edge." Since we are destined to meet here, I hope you have a certain understanding and understanding, but also can pay attention to the small part, so that will not
