It's part of that strange hack to get sprintf and sscanf to work sort of the
same way (f)printf and (f)scanf do.  The routines invent a FILE structure, 
call common routines with that FILE structure's address, and set _IOSTRG in
the flags field to get some special-casing in the common routines.

I hope to God there isn't one.
