linux mutex example

Mutex is a key. When a person takes the key, they can enter a room. When they come out, the key is handed over to the first in the queue. Generally, this method is used to serialize the access to the critical section code to ensure that the Code is

1. Synchronization of threads with mutex 1.1. Mutex for threadsA set of mutex functions specifically for thread mutexes is defined in the POSIX thread. A mutex is a simple locking method to control access to a shared resource, which has only two

Anyone who has worked on a slightly larger project knows that they strive for program stability and convenient scheduling and use a large number of threads. Almost every module has a dedicated thread processing function. The mutex and condition

I. mutex lock In essence, mutex is a lock that provides protection for access to shared resources. 1. Initialization: In Linux, the thread mutex data type is pthread_mutex_t. Before use, initialize it: For the mutex of static allocation, you can set

Analysis of Inter-thread Communication 1: mutex and condition Variables The purpose of thread synchronization is to ensure data consistency. In Linux, common thread synchronization methods include mutex, read/write locks, and conditional variables.

A process is an object for Linux Resource Allocation. Linux allocates virtual memory (4 GB), file handle, and other resources to the process. It is a static concept. LineIs the object of CPU scheduling and a dynamic concept. A process must contain

. Thread Access MechanismThere are two kinds of relationship between tasks: 1, indirect relationship, 2, direct relationship.For example 1. Task A writes to the MO buffer. Task B reads from this buffer. Then the relationship between A and B is a
