IDA Pro: function to return first valid address

Question

The IDA Pro Python function ScreenEA() will return the address the cursor is at and if I manually position the cursor at the start, it will return the first valid address.

However, I would like to be able to position my cursor anywhere and be able to ask for what the first valid address is. What function will return that information?

Answer 1

You'd want to use MinEA(), which is equivalent to GetLongPrm(INF_MIN_EA).

From IDA's documentation:

INF_MIN_EA      // int32; The lowest address used
                //        in the program
