pthread

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

#include <pthread.h>
#include <stdio.h>
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 finishprintf("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
