You can't. #pragmas are compiler directives and used internally by the C/C++ compiler, there is nothing in the object code to identify how they have been used.

Hmmm.... If you check the link provided by me, there is a way. But I am not sure if the OP wants it in that way. I have coded as said in that article and the value is in fact coming as warning in output window in VS

"warning C4810: value of pragma pack(show) == 4"

I have used #pragma pack(4) earlier

It is still only available during the compilation phase so I think my answer stands. Of course, the question is so vague (like so many here) that it is almost unanswerable, I don't really know what the OP wants to know or why.

Yup. You have a point. A 5 for your solution
