获取线程信息/环境块(TIB/TEB)的官方方法 [英] Official way to get the Thread Information/Environment Block (TIB/TEB)

问题描述

在 Windows 中，如果没有记录，可以在 FS:0 中找到当前线程的线程信息块 (TIB) 是很常见的知识.但这仅适用于英特尔 CPU，其中 FS 寄存器首先存在.现在我想在基于 ARM 的 Windows 系统(Windows Phone 和 Windows RT)上访问 TIB.请问有相关的API吗?

In Windows, it's long been common, if undocumented, knowledge that the Thread Information Block (TIB) of the current thread can be found at FS:0. But that only works on Intel CPUs, where the FS register exists in the first place. Now I wanna get to the TIB on an ARM-based Windows system (Windows Phone and maybe Windows RT). Is there an API for that, please?

我想获取用于崩溃报告的线程堆栈基础.

推荐答案

宏 NtCurrentTeb() 在 winnt.h 中可用于所有支持的架构，包括 ARM (Windows RT):

The macro NtCurrentTeb() is available in winnt.h for all supported architectures, including ARM (Windows RT):

#if defined(_M_ARM) && !defined(__midl) && !defined(_M_CEE_PURE)

__forceinline
struct _TEB *
NtCurrentTeb (
    VOID
    )
{
    return (struct _TEB *)(ULONG_PTR)_MoveFromCoprocessor(CP15_TPIDRURW);
}
