如何以编程方式区分虚拟机中的GPT动态和GPT基本磁盘

Recently I had to find out a way to differentiate what partition type the virtual machine used,Reading the raw data from the virtual disk I was able to find it by checking with offset 1C2 (EE in case of GPT), in case of MBR disk if the disk is dynamic the offset at 1C2 had 42 and in case of basic disk the same 1C2 offset had 07 which means basic disk , now If it is a GPT disk how do I differentiate between basic and dynamic disks.Recently I had to find out a way to differentia
