Edit Question
Title
Body
Is there any way to use a sizeof in a preprocessor macro? For example, there have been a ton of situations over the years in which I wanted to do something like: #if sizeof(someThing) != PAGE_SIZE #error Data structure doesn't match page size #endif The exact thing I'm checking here is completely made up - the point is, I often like to put in these types of (size or alignment) compile-time checks to guard against someone modifying a data-structure which could misalign or re-size things which would break them. Needless to say - I don't appear to be able to use a sizeof in the manner described above.
