Determine processor support for SSE2?

Question

I need to do determine processor support for SSE2 prior installing a software. From what I understand, I came up with this:

bool TestSSE2(char * szErrorMsg)
         


        

Answer 1

I found this one by accident in the MSDN:

BOOL sse2supported = ::IsProcessorFeaturePresent( PF_XMMI64_INSTRUCTIONS_AVAILABLE );

Windows-only, but if you are not interested in anything cross-platform, very simple.
