Constant address of function

You normally don't place a C function at a fixed address. You normally place it in a segment, and let the linker place the segment at a fixed address.

But as Andy notes, it is more or less impossible to help people if the original question doesn't explicitly says why a specific request is made, or give enough facts to allow us to deduce why you are making the question.

A large percent of the questions can have an answer - but that answer would be wrong, since the original question was wrong to begin with. A very, very large part of questions about absolute addresses falls within this category. So always mention if you are talking about the entry point for a bootloader-retrieved application, a monitor-accessible entry point or whatever you are trying to implement.
