In the thread synchronization process, there are also the following situations: Thread A needs to wait for A condition to be established before it can continue to run. if the condition is not true, thread A will be blocked, when thread B sets this

The biggest feature of threads is resource sharing, but the synchronization problem in resource sharing is the difficulty of multi-thread programming. In linux, multiple methods are provided to process thread synchronization. The biggest feature of

The so-called concurrent server is at the same time can handle requests from multiple clients; A circular server is a request that the server can respond to only one client at a time. And for TCP and UDP sockets, the two servers are implemented in

"Problem description"Zuma is a once-popular global game, the play is: in a track initially lined with a number ofColored beads, where any three adjacent beads are not exactly the same color. After that, you can launch beads toTrack and add the

The so-called concurrent server is at the same time can handle requests from multiple clients; A circular server is a request that the server can respond to only one client at a time. And for TCP and UDP sockets, the two servers are implemented in

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

Most people who have studied single-chip microcomputer know the names of "Water lamp" or "horse lamp". The specific implementation effect is to display a group of changes cyclically according to a fixed rule. For example, if you use a byte length

Multi-process has a file F for the classic problem of shared resource mutex access and process synchronization. multiple concurrent read and write processes must be accessed. Requirements: (1) read/write mutex (2) write/Write mutex (3) allows

The linked list is an important part of the data structure and is widely used in computer programs. It is also the focus of PEN questions of various companies. The following are some simple operations for the linked list, including creating, adding,

In network programs, a server is usually used to process multiple clients. In order to make requests from multiple clients, the server programs have different processing methods. Currently, the most common server models are as follows: Cyclic server:

/******************** Server Model **************** **/ 1. Cyclic server: the cyclic server can only respond to one client request at a time; 2. Concurrent Server: the concurrent server can request multiple clients at the same time. ***********

The condition variable is another way of thread synchronization, in fact, the condition variable is the underlying implementation of the semaphore, which means that the use of conditional variables can have greater degrees of freedom, but also
