marker_position (BVAR (current_buffer, mark)) is it.  Why does it look
wrong to you?

And why do you need the first condition?

And why do you need to access the mark in the first place?  It is rare
for the C code to need that; about the only place where we do it is in
interpreting the 'interactive' codes.
