C语言--以pthread为例建立一个h文件测试代码

pthread

1、新建一个demoC
CMakeLists.txt加入依赖
target_link_libraries(demoC -pthread)
2、依赖
#include
#include
3、定义头文件
pthread_test.h
头文件中定义函数

#include 
#include 
void *thread_function(void *arg);
/**
 * 创建新的线程
 * @return
 */
int create_new_thread(void);

4、实现头文件中定义的函数
pthread_test.c

#include "pthread_test.h"
void *thread_function(void *arg) {
    printf("Hello from the new thread!\n");
    return NULL;
}
/**
 * 测试创建一个线程
 * @return
 */
int create_new_thread(void){
    pthread_t thread_id;
    int result = pthread_create(&thread_id, NULL, thread_function, NULL);
    if (result != 0) {
        perror("Thread creation failed");
        return 1;
    }
    printf("Main thread: Created a new thread with ID %lu\n", thread_id);
    pthread_join(thread_id, NULL); // Wait for the new thread to finish
    printf("Main thread: New thread has terminated\n");
    return 0;
}

5、运行
引入自定义头文件
实现main

#include "pthread_test.h"
int main() {
    create_new_thread();
    return 0;
}

运行结果

Main thread: Created a new thread with ID 139967580378880
Hello from the new thread!
Main thread: New thread has terminated
