有没有办法用C语言同时运行两个程序并记录输出

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

void* program1(void* arg) {
    // 程序1的逻辑
    printf("Program 1 is running.\n");
    return NULL;
}

void* program2(void* arg) {
    // 程序2的逻辑
    printf("Program 2 is running.\n");
    return NULL;
}

int main() {
    pthread_t thread1, thread2;

    // 创建线程1，运行程序1
    pthread_create(&thread1, NULL, program1, NULL);

    // 创建线程2，运行程序2
    pthread_create(&thread2, NULL, program2, NULL);

    // 等待线程1和线程2结束
    pthread_join(thread1, NULL);
    pthread_join(thread2, NULL);

    return 0;
}
