linux 向线程传参数

int pthread_create(pthread_t *thread, const pthread_attr_t *attr, void *(*start_routine) (void *), void *arg);

#include <pthread.h>
#include <stdio.h>
#include <stdlib.h>

// 定义一个结构体用于传递多个参数
typedef struct {
    int num;
    char *str;
} thread_data_t;

// 线程执行的函数
void* thread_func(void *arg) {
    thread_data_t *data = (thread_data_t *)arg;
    printf("Thread received: num = %d, str = %s
", data->num, data->str);
    pthread_exit(NULL);
}

int main() {
    pthread_t thread_id;
    thread_data_t data;

    // 初始化参数
    data.num = 10;
    data.str = "Hello from main thread";

    // 创建线程并传递参数
    if (pthread_create(&thread_id, NULL, thread_func, (void *)&data) != 0) {
        perror("pthread_create");
        exit(EXIT_FAILURE);
    }

    // 等待线程结束
    pthread_join(thread_id, NULL);

    return 0;
}
