有没有纯AU3方法或API方法获取当前分区是否GPT格式的思路？-已解决问题区-AUTOIT CN

https://msdn.microsoft.com/zh-cn/library/windows/desktop/aa364003(v=vs.85).aspx
DRIVE_LAYOUT_INFORMATION_GPT structure
Contains information about a drive's GUID partition table (GPT) partitions.
Syntax

C++

typedef struct _DRIVE_LAYOUT_INFORMATION_GPT {
GUID DiskId;
LARGE_INTEGER StartingUsableOffset;
LARGE_INTEGER UsableLength;
ULONG MaxPartitionCount;
} DRIVE_LAYOUT_INFORMATION_GPT, *PDRIVE_LAYOUT_INFORMATION_GPT;

这参数不错，可惜不弄C++ ，虫子的出现总会带来惊喜{:face (356):}

这段代码似乎和P版很像，而且好像没有P版的全面。

因为没有GPT的环境，虚拟机搭建了一个。好不容易整出GPT分区。用P版的代码，完全可以胜任。老外那个在P版的代码里都包含了，而且P版的更全面。MBR，GPT硬盘完全检测出。

看看22楼，磁盘编号我自己加的，可能有点错误，应该是2：1，2：2，2：3
