Mac枚举串口列表失败，getSerialPath有Bug

[xxCabin]

/描述bug Mac枚举串口失败 `char getSerialPath(char dest, io_object_t &serialPort) { CFTypeRef calloutCFString;

calloutCFString = IORegistryEntryCreateCFProperty(serialPort, CFSTR(kIOCalloutDeviceKey), kCFAllocatorDefault, 0);

if (calloutCFString)
{
    // sizeof(dest) = 8bytes, can not copy all bytes
    // CFStringGetCString(static_cast<CFStringRef>(calloutCFString), dest, sizeof(dest), kCFStringEncodingUTF8);

    CFStringGetCString(static_cast<CFStringRef>(calloutCFString), dest, MAXPATHLEN, kCFStringEncodingUTF8);

    CFRelease(calloutCFString);
}

return dest;

}`

重现步骤 mac下，调用getPortInfoList 预期行为 无 截图

运行环境信息:

• 操作系统: mac12.6.3
• 编译器:xcode 14.0
