在Linux C中，使用pthread库创建线程的步骤如下：，，1. 包含必要的头文件：#include，2. 定义线程函数：void *thread_function(void *arg) { /* 线程代码 */ return NULL; }，3. 创建线程：int pthread_create(pthread_t *thread, const pthread_attr_t *attr, void *(*start_routine) (void *), void *arg);，4. 等待线程结束：int pthread_join(pthread_t thread, void **retval);，5. 编译时链接pthread库：gcc -o program program.c -lpthread，，，，``c，#include，#include，#include，，void *print_message_function(void *ptr) {， char *message;， message = (char *) ptr;， printf("%s ，", message);， return NULL;，}，，int main() {， pthread_t thread1, thread2;， char *message1 = "Thread 1";， char *message2 = "Thread 2";， int iret1, iret2;，， iret1 = pthread_create(&thread1, NULL, print_message_function, (void*) message1);， iret2 = pthread_create(&thread2, NULL, print_message_function, (void*) message2);，， pthread_join(thread1, NULL);， pthread_join(thread2, NULL);，， printf("Thread 1 returns: %d，", iret1);， printf("Thread 2 returns: %d，", iret2);，， exit(0);，}，``
