在前面的博文《驱动开发：Win10内核枚举SSDT表基址》中已经教大家如何寻找SSDT表基地址了，找到后我们可根据序号获取到指定SSDT函数的原始地址，而如果需要输出所有SSDT表信息，则可以定义字符串列表，以此循环调用GetSSDTFunctionAddress()函数得到，当然在此之间也可以调用系统提供的MmGetSystemRoutineAddress()函数顺便把当前地址拿到，并通过循环方式得到完整的SSDT列表。
当调用 MmGetSystemRoutineAddress() 函数时，你只需要将函数名字符串通过 RtlInitUnicodeString() 函数格式化为 UNICODE_STRING 结构，然后将该结构传递给 MmGetSystemRoutineAddress() 函数。该函数将会返回函数的地址。
在下面的示例中，我们将通过 RtlInitUnicodeString() 函数将函数名字符串格式化为 UNICODE_STRING 结构，并使用 MmGetSystemRoutineAddress() 函数获取 NtOpenFile 函数的地址：
// 署名权
// right to sign one's name on a piece of work
// PowerBy: LyShark
// Email: me@lyshark.com
#include <ntifs.h>
VOID UnDriver(PDRIVER_OBJECT driver)
{
DbgPrint(("驱动程序卸载成功! \n"));
}
NTSTATUS DriverEntry(PDRIVER_OBJECT DriverObject, PUNICODE_STRING RegistryPath)
{
DbgPrint("hello lyshark.com \n");
// 获取SSDT起源地址
UNICODE_STRING uncode;
RtlInitUnicodeString(&uncode, L"NtOpenFile");
PULONGLONG source_address = MmGetSystemRoutineAddress(&uncode);
DbgPrint("[LyShark] NtOpenFile起源地址 = %p \n", source_address);
DriverObject->DriverUnload = UnDriver;
return STATUS_SUCCESS;
}代码获得NtOpenFile这个函数的内存地址，输出效果如下所示：
根据上一章节的内容扩展，枚举完整SSDT表我们可以这样来实现，通过将完整的SSDT结构字符串放入到SSDT变量内，然后通过不间断的循环取出每一个SSDT函数的相对地址信息。如下所示；
// 署名权
// right to sign one's name on a piece of work
// PowerBy: LyShark
// Email: me@lyshark.com
#include <ntifs.h>

}我们运行这段程序，即可得到整个系统中所有的SSDT表地址信息；
在WinDBG中可看到完整的输出内容，当然有些函数没有被导出，起源地址是拿不到的。
