检测windows 32位程序是否运行在64位系统上

摘自MSDN的IsWow64Process说明

 

#include <windows.h> #include <stdio.h> typedef BOOL (WINAPI *LPFN_ISWOW64PROCESS) (HANDLE, PBOOL); LPFN_ISWOW64PROCESS fnIsWow64Process; BOOL IsWow64() { BOOL bIsWow64 = FALSE; fnIsWow64Process = (LPFN_ISWOW64PROCESS)GetProcAddress( GetModuleHandle(TEXT("kernel32")),"IsWow64Process"); if (NULL != fnIsWow64Process) { if (!fnIsWow64Process(GetCurrentProcess(),&bIsWow64)) { // handle error } } return bIsWow64; } void main() { if(IsWow64()) printf("Running on WOW64/n"); else printf("Running on 32-bit Windows/n"); }
