I’m trying to determine if the current system is 32 or 64 bit. And I want to get that info from the SystemInfo, but it VS gives me error’s when I try to compile this. I can’t use most other methods to determine if the OS is 64 or 32 bit. Because I need to check if windows is 64 bit and not the process.

LPSYSTEM_INFO info;
GetSystemInfo(&info); // Error

IntelliSense: argument of type “LPSYSTEM_INFO *” is incompatible with parameter of type “LPSYSTEM_INFO”

error C2664: ‘GetSystemInfo’ : cannot convert parameter 1 from ‘LPSYSTEM_INFO *’ to ‘LPSYSTEM_INFO’

    Your info buffer should be of type SYSTEM_INFO, not LPSYSTEM_INFO. When you capture its address with &info you’ll get the LPSYSTEM_INFO pointer you need to pass into GetSystemInfo.

    (In case it’s not clear LPSYSTEM_INFO is a typedef, aliased to SYSTEM_INFO *.)
