What is the lock?
To see some articles, often used as a multithreaded, speaking, reading and writing lock
So what is the lock?
Are there any standard c + +? (c + + library definition)
What is the mechanism of lock (what is the principle)?
PS: can you send some articles let me consider

CodePudding user response:

1. C + + standard library, a lock is located in the header file mutex,
2. For example, you go to the toilet suddenly rushed in and afraid of others? Most people are afraid of, so the public toilet generally have a lock, computer lock of also is such, is because of the lock, and makes some operating part can monopolize the resources

Thank you, but you have what good article?

Is for the exclusive lock, it system resources are Shared, but some resources sharing conflict happens, locking resources, then locked resources can only by the owner of the lock to enjoy alone, other users have to wait for the lock release,
Lock mutex header file defines some standard
Type and principle of the lock can refer to
