Linux“在程序中使用线程”实验的实验步骤

下面是一个在Linux中使用线程的实验步骤:
1. 创建一个C语言程序文件,命名为“thread.c”,并在其中包含必要的头文件,如下所示:
```
#include <stdio.h>
#include <stdlib.h>
#include <pthread.h>
```
2. 在main函数中创建一个线程,使用pthread_create函数。这个线程将调用一个名为"thread_function"的函数。如下所示:
```
void *thread_function(void *arg)
{
printf("Thread is running.\n");
return NULL;
}
int main()
{
pthread_t my_thread;
if (pthread_create(&my_thread, NULL, thread_function, NULL)) {
printf("Error creating thread.\n");
abort();
}
printf("Main thread is running.\n");
pthread_exit(NULL);
}
```
3. 使用pthread_join函数等待线程执行完毕。如下所示:
```
int main()
{
pthread_t my_thread;
if (pthread_create(&my_thread, NULL, thread_function, NULL)) {
printf("Error creating thread.\n");
abort();
}
printf("Main thread is running.\n");
pthread_join(my_thread, NULL);
printf("Thread has finished.\n");
pthread_exit(NULL);
}
```
4. 编译并运行程序。在Linux命令行中,使用以下命令进行编译:
```
gcc -o thread thread.c -lpthread
```
这将生成一个名为“thread”的可执行文件。使用以下命令运行程序:
```
./thread
```
这将启动程序并输出以下内容:
```
Main thread is running.
Thread is running.
Thread has finished.
```
这表明主线程和新线程都已成功运行,并且新线程已经完成。
以上就是在Linux中使用线程的实验步骤。
