termios Q (tcsetattr() when using stdio)

[Paul Evans]

Hi All,

After converting by BSP to termios (mainly for application
portability), I now can't figure out what the portable way of
doing a tcsetattr() is if I'm using libc stdio. Or more
specifically can I get a "int " file handle from a "FILE *"
stream pointer?

I guessing the answer is to open the file twice,
as a stream and using libio? Or could I 
open/tcsetsttr/close then go ahead and 
use streams knowing that the termios state
would stay intact? (Is this portable?)

And Yes I know I might look inside the FILE 
structure itself, but then the portability gods might
strike me down. I'd rather skip fprintf in leu of 
snprintf and write() the buffer.

Questions Questions...


Thanks,

    -Paul
