将多个参数传递给C中的线程(pthread_create)

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

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

// 定义一个结构体，用于传递多个参数
typedef struct {
    int param1;
    float param2;
    char param3;
} ThreadParams;

// 线程函数，接收一个参数为ThreadParams类型的指针
void* threadFunc(void* arg) {
    ThreadParams* params = (ThreadParams*)arg;
    printf("param1: %d\n", params->param1);
    printf("param2: %f\n", params->param2);
    printf("param3: %c\n", params->param3);
    // 线程执行的逻辑
    // ...
    return NULL;
}

int main() {
    pthread_t thread;
    ThreadParams params = { 10, 3.14, 'A' };

    // 创建线程并传递参数
    pthread_create(&thread, NULL, threadFunc, (void*)&params);

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

    return 0;
