不过,理论上来说,也可以用一个int的大小作为参考,
判断是32位还是64位.
sizeof(int) == 4 //32位系统.
sizeof(int) == 8 //64位系统.
也可以使用函数如下:
BOOL IsWow64() { typedef BOOL (WINAPI *LPFN_ISWOW64PROCESS) (HANDLE, PBOOL); LPFN_ISWOW64PROCESS fnIsWow64Process; BOOL bIsWow64 = FALSE; fnIsWow64Process = (LPFN_ISWOW64PROCESS)GetProcAddress( GetModuleHandle("kernel32"),"IsWow64Process"); if (NULL != fnIsWow64Process) { fnIsWow64Process(GetCurrentProcess(),&bIsWow64); } return bIsWow64; }
