"Analysis of the Implementation Principle of Go Statement in C Language"
The Go statement is a keyword in the Go language and is used to implement concurrent execution tasks. In C language, we can implement functions similar to Go statements by using threads and multi-threading libraries. This article will introduce how to implement functions similar to Go statements in C language, and explain its implementation principles through specific code examples.
In C language, we can use the thread library pthread to create threads, and simulate the functions of Go statements through the creation and management of threads. The specific implementation steps are as follows:
- Create threads: We first need to create threads through the pthread_create function of the pthread library. After the thread is created, we pass the thread function as a parameter to the pthread_create function. The thread function is the task we want to execute concurrently.
- Thread function: Thread function is the actual implementation of the tasks we want to execute concurrently. In thread functions, we can write specific task logic, such as calculations, I/O operations, etc.
- Thread management: Once the thread is created successfully, we need to use other functions in the pthread library to manage the execution of the thread. For example, you can use the pthread_join function to wait for the end of the thread and obtain the return value of the thread.
The following uses a specific code example to illustrate how to implement functions similar to Go statements in C language:
#include <stdio.h>
#include <pthread.h>
void* thread_function(void* arg) {
int thread_id = *((int*)arg);
printf("Thread %d is running
", thread_id);
// 執(zhí)行具體任務(wù)邏輯
for (int i = 0; i < 5; i++) {
printf("Thread %d: %d
", thread_id, i);
}
return NULL;
}
int main() {
pthread_t thread1, thread2;
int thread_id1 = 1, thread_id2 = 2;
pthread_create(&thread1, NULL, thread_function, &thread_id1);
pthread_create(&thread2, NULL, thread_function, &thread_id2);
pthread_join(thread1, NULL);
pthread_join(thread2, NULL);
return 0;
}In the above code example, we first define a Thread function thread_function, this function simulates the task logic of concurrent execution. Then in the main function, we create two threads thread1 and thread2 and pass the thread function thread_function as a parameter to the pthread_create function. Finally, use the pthread_join function to wait for the end of the thread.
Through the above code examples, we can see how to use the thread library pthread in C language to implement functions similar to Go statements and achieve the effect of concurrent execution of tasks. In actual applications, the thread creation and management methods can be adjusted according to specific needs and task logic to achieve the best concurrent execution effect.

C language data structure: data representation and operation of trees and graphs
Apr 04, 2025 am 11:18 AM
C language data structure: The data representation of the tree and graph is a hierarchical data structure consisting of nodes. Each node contains a data element and a pointer to its child nodes. The binary tree is a special type of tree. Each node has at most two child nodes. The data represents structTreeNode{intdata;structTreeNode*left;structTreeNode*right;}; Operation creates a tree traversal tree (predecision, in-order, and later order) search tree insertion node deletes node graph is a collection of data structures, where elements are vertices, and they can be connected together through edges with right or unrighted data representing neighbors.
How debian readdir integrates with other tools
Apr 13, 2025 am 09:42 AM
The readdir function in the Debian system is a system call used to read directory contents and is often used in C programming. This article will explain how to integrate readdir with other tools to enhance its functionality. Method 1: Combining C language program and pipeline First, write a C program to call the readdir function and output the result: #include#include#include#includeintmain(intargc,char*argv[]){DIR*dir;structdirent*entry;if(argc!=2){
The truth behind the C language file operation problem
Apr 04, 2025 am 11:24 AM
The truth about file operation problems: file opening failed: insufficient permissions, wrong paths, and file occupied. Data writing failed: the buffer is full, the file is not writable, and the disk space is insufficient. Other FAQs: slow file traversal, incorrect text file encoding, and binary file reading errors.
How to understand ABI compatibility in C?
Apr 28, 2025 pm 10:12 PM
ABI compatibility in C refers to whether binary code generated by different compilers or versions can be compatible without recompilation. 1. Function calling conventions, 2. Name modification, 3. Virtual function table layout, 4. Structure and class layout are the main aspects involved.
Detailed introduction to each directory of Linux and each directory (reprinted)
May 22, 2025 pm 07:54 PM
[Common Directory Description] Directory/bin stores binary executable files (ls, cat, mkdir, etc.), and common commands are generally here. /etc stores system management and configuration files/home stores all user files. The root directory of the user's home directory is the basis of the user's home directory. For example, the home directory of the user user is /home/user. You can use ~user to represent /usr to store system applications. The more important directory /usr/local Local system administrator software installation directory (install system-level applications). This is the largest directory, and almost all the applications and files to be used are in this directory. /usr/x11r6?Directory for storing x?window/usr/bin?Many

How to calculate list length in Python?
May 23, 2025 pm 10:30 PM
The easiest way to calculate list length in Python is to use the len() function. 1) The len() function is suitable for lists, strings, tuples, dictionaries, etc., and returns the number of elements. 2) Although custom length calculation function is feasible, it is inefficient and is not recommended to use it in practical applications. 3) When processing large data sets, you can first calculate the length to avoid repeated calculations and improve performance. Using the len() function is simple, fast and reliable, and is the best practice for calculating list lengths.
