Do we have any portable way of reading stdio
and writing stdio (in sessions where it exists)
on a character by character basis?

In other words do we have anything better than my
currently unwritten and untested code which

[1]  uses 'msvcrt.dll' (windows), '/lib/libc.so.6' (linux), or ??? (mac)

[2] uses fopen to get file handles, from
  ('/dev/stdin' and '/dev/stdout' on linux, 'con' on
windows and ??? on mac)

[2] uses getc() for input and putc() for output

Thanks,
