I think you have good idea here. Which is definitly better than what i
was thinking.

Due to C's left to right argument passing, and the caller responsible
for clearing the stack (if used), it would work just by changing the new
fdevopen putc callback declaration from

int (*__put)(FILE *, char)

to

int (*__put)(char, FILE *)

which happends to be consisten with fputc.
