C++ LibpCap禁用监视器模式(C、MacOS)

我有一个功能，可以使用libpCap在MacOS上为WiFi设备启用监控模式.这是可行的，但目前将WiFi设备设置回托管模式的唯一方法是退出该进程.我希望将WiFi设备设置为托管模式，同时允许该过程继续.据我所知，这不能用libpcap.我如何将WiFi设备设置回托管模式(可能使用Objective-C中的CoreWLAN API？)？

pcap_t *enable_monitor(char *dev) {
    wifi_disassociate();

    char error_buffer[PCAP_ERRBUF_SIZE];
    pcap_t *handle;
    int result;

    handle = pcap_create(dev, error_buffer);
    if (handle == NULL) {
        printf("failed to create a handle: %s\n",
               error_buffer);
        return NULL;
    }
    result = pcap_set_rfmon(handle, 1);
    if (result != 0) {
        printf("failed to set pcap rfmon: %s (%s)\n",
               pcap_statustostr(result),
               pcap_geterr(handle));
        return NULL;
    }
    result = pcap_activate(handle);
    if (result != 0) {
        printf("failed to activate handle: %s (%s)\n",
               pcap_statustostr(result),
               pcap_geterr(handle));
        return NULL;
    }
    //pcap_close(handle);
    return handle;
}

编辑: 将第二个参数设置为cap_set_rfmon到0似乎并没有将设备设置为托管模式，只是没有将其设置为监视模式.

int disable_monitor(pcap_t *handle) {
    int result;
    result = pcap_set_rfmon(handle, 0);
    if (result != 0) {
        printf("failed to set pcap rfmon: %s (%s)\n",
               pcap_statustostr(result),
               pcap_geterr(handle));
        return 1;
    }
    pcap_close(handle);
    return 0;
}

int main() {
    char *dev = find_wifi_device();
    pcap_t *handle = enable_monitor(dev);
    sleep(5);
    int status = disable_monitor(handle);
    printf("Status: %d\n", status);
    for (;;)
        sleep(100);
}

这将导致:

failed to set pcap rfmon: The setting can't be changed after the pcap_t is activated (can't perform  operation on activated capture)
Status: 1
