写两个C++程序，使用socketCAN原理程序1发送标准帧报文ABCDABCD程序2接受该报文

好的，这是一个技术问题，我可以尝试回答。

对于程序1发送标准帧报文ABCDABCD，可以使用如下代码：

#include <stdio.h>
#include <string.h>
#include <net/if.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <linux/can.h>
#include <linux/can/raw.h>

int main()
{
    int s;
    struct sockaddr_can addr;
    struct ifreq ifr;
    struct can_frame frame;

    const char* ifname = "can0"; // 使用的CAN接口
    memset(&ifr, 0, sizeof(ifr));
    strncpy(ifr.ifr_name, ifname, sizeof(ifr.ifr_name)); 

    // 创建套接字并绑定到CAN接口
    s = socket(PF_CAN, SOCK_RAW, CAN_RAW);
    setsockopt(s, SOL_CAN_RAW, CAN_RAW_FILTER, NULL, 0);
    addr.can_family = AF_CAN;
    addr.can_ifindex = ifr.ifr_ifindex;
    bind(s, (struct sockaddr*)&addr, sizeof(addr));

    // 准备CAN帧数据
    memset(&frame, 0, sizeof(frame));
    frame.can_id = 0x123;
    frame.can_dlc = 8;
    memcpy(frame.data, "ABCDABCD", 8);

    // 发送CAN帧数据
    write(s, &frame, sizeof(frame));

    return 0;
}

对于程序2接收该报文，可以使用如下代码：

#include <stdio.h>
#include <string.h>
#include <net/if.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <linux/can.h>
#include <linux/can/raw.h>

int main()
{
    int s;
    struct sockaddr_can addr;
    struct ifreq ifr;
    struct can_frame frame;

    const char* ifname = "can0"; // 使用的CAN接口
    memset(&ifr, 0, sizeof(ifr));
    strncpy(ifr.ifr_name, ifname, sizeof(ifr.ifr_name)); 

    // 创建套接字并绑定到CAN接口
    s = socket(PF_CAN, SOCK_RAW, CAN_RAW);
    setsockopt(s, SOL_CAN_RAW, CAN_RAW_FILTER, NULL, 0);
    addr.can_family = AF_CAN;
    addr.can_ifindex = ifr.ifr_ifindex;
    bind(s, (struct sockaddr*)&addr, sizeof(addr));

    // 接收CAN帧数据
    while (1) {
        int nbytes = read(s, &frame, sizeof(frame));
        if (nbytes < 0) {
            perror("can raw socket read");
            return 1;
        }
        else if (nbytes < sizeof(struct can_frame)) {
            fprintf(stderr, "read: incomplete CAN frame\n");
            return 1;
        }
        else {
            if (frame.can_id == 0x123 && frame.can_dlc == 8 && memcmp(frame.data, "ABCDABCD", 8) == 0) {
                printf("Received requested CAN frame on interface %s\n", ifname);
            }
            else {
                printf("Received CAN frame with ID 0x%x and DLC %d\n", frame.can_id, frame.can_dlc);
            }
        }
    }

    return 0;
}

注意需要根据实际情况修改CAN接口名称和CAN帧的ID、DLC、数据等内容。
