在dalsa相机提供的GigE-V-Framework_aarch64_2.20.0.0181.tar.gz的sdk中，我想把相机数据取出通过udo协议发送出去怎么做，代码

以下是一个示例代码，它使用GigE-V-Framework SDK将图像数据从相机中提取出来，并通过UDP协议发送出去。请注意，这只是一个示例代码，您需要根据您的具体情况进行修改和适配。

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <arpa/inet.h>
#include <sys/socket.h>
#include <time.h>
#include <unistd.h>
#include <Dalsa/GevApi.h>
#include <Dalsa/GigEVision.h>

#define MAX_PACKET_SIZE 1472 // Max UDP packet size
#define PORT 8888 // Port number for UDP communication

int main(int argc, char *argv[]) {
    // Initialize GigE-V Framework
    GevApiInitialize();

    // Open camera
    GEV_DEVICE_INTERFACE device;
    GEV_CAMERA_HANDLE handle;
    GEV_DEVICE_INFO device_info;
    memset(&device, 0, sizeof(device));
    memset(&handle, 0, sizeof(handle));
    memset(&device_info, 0, sizeof(device_info));
    device.macLow = 0x10;
    device.macHigh = 0x00;
    handle = GevOpenCamera(&device, GevExclusiveMode);
    if (handle == NULL) {
        printf("Failed to open camera.\n");
        return -1;
    }

    // Get camera information
    GevGetCameraInfo(handle, &device_info);

    // Configure camera

            // Send image via UDP
            int num_packets = (image_size + MAX_PACKET_SIZE - 1) / MAX_PACKET_SIZE; // Calculate the number of packets needed to transmit the image
            int last_packet_size = image_size - (num_packets - 1) * MAX_PACKET_SIZE; // Calculate the size of the last packet
            uint8_t *packet_buffer = (uint8_t *) malloc(MAX_PACKET_SIZE);
            for (int i = 0; i < num_packets; i++) {

                    printf("Error sending UDP packet.\n");
                }
            }
            free(packet_buffer);
        } else {
            printf("Error getting image.\n");
        }
    }

    // Stop image acquisition
    GevStopTransfer(handle);

    // Free memory
    GevFreeImageBuffer(&image_buffer);
    GevCloseCamera(&handle);
    GevApiUninitialize();
