Reference case: https://www.cnblogs.com/myseries/p/10918819.html 1. Thread interrupt Interrupt ing a thread means stopping everything it is doing before it completes its task, effectively aborting its current operation. Whether the thread dies, waits for a new task, or continues to run to the next step depends on the program. Although it may se ...

Deeply understand the communication between threads of concurrent programming 1, What is thread communication Communication between threads is to enable threads to send signals to each other. When multiple threads are processing the same resource and the tasks are different (normally, multi-threaded execution is processed at the same ti ...

Concurrent reading and writing of vectorAs we all know, vector in C + + standard library does not guarantee thread safety. When we read and write vectors concurrently, we often face two risks:Content reading exception: for example, two threads are reading, one is writing, or two threads are writing at the same time, which will lead to inconsist ...

Process and thread concept Process: a process is an execution process of a program. It is the basic unit for allocating and managing resources during program execution. Each process has its own memory space. Thread: thread is the basic unit of CPU resource scheduling and allocation. It can share process resources with other threads in th ...

Multithreading Thread related concepts Program It is a set of instructions written in a certain language to complete a specific task. Simply put: it's the code we wrote process Process refers to a running program, such as QQ, which starts a process, and the operating system will allocate memory space for the process. When we use Xunlei ...

Thread overview Thread is a lightweight process (LWP). In Linux environment, the essence of thread is still a process. The program running on the computer is a combination of a group of instructions and instruction parameters. The instructions control the computer according to the established logic. The operating system will allocate syste ...
