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

The most basic way to check for SSE2 support is by using the CPUID instruction (on platforms where it is available). Either using inline assembly or using compiler intrinsics.
