Hi,
I'm looking to receive some kind of compile-time notification if a structure size isn't what I'd expect it to be. Something like:
#IF SIZEOF(MyStructType) != 100 DISPLAY "Oops, there's problem"
You can't do this with the preprocessor since it doesn't have info on types. However, you can do this with the compiler by writing something like:
typedef int TEST_MYSTRUCT_SIZE[sizeof(MyStructType)] == 100];
If the expression inside the array bounds is false, it will evaluate to 0 which is an invalid array size. Otherwise, it will be 1, and you'll just be left with an unused typedef.
