是否有 Windows API 调用会告诉我我是否在 64 位操作系统上运行? [英] Is there a Windows API call that will tell me if I'm running on a 64-bit OS?

问题描述

是否有 Windows API 调用会告诉我我是否在 64 位操作系统上运行?我有一些遗留的 C++ 代码，它调用 GetVersionEx 来填充 OSVERSIONINFO 结构，但这仅告诉我(AFAIK)操作系统(Vista、V7 等)，而不是处理架构.我可以通过简单地寻找C:\Program Files (x86)..."的存在来解决这个问题，但这看起来很难看.我确定必须有一个 API 来返回此信息.

解决方案

IsWow64Process 可能就是您要找的.

Is there a Windows API call that will tell me if I'm running on a 64-bit OS? I have some legacy c++ code that makes a call to GetVersionEx to fill in a OSVERSIONINFO structure, but that only tells me (AFAIK) the OS (Vista, V7, etc.), but not the processing architecture. I can hack around this by simply looking for the existence of "C:\Program Files (x86)...", but this seems ugly. I'm sure there must be an API to return this info.

解决方案

IsWow64Process might be what you are looking for.
