The proposed ANSI standard provides

    setvbuf (file, NULL, _IONBF, 0)

for setting non-buffered mode on a file.  This would be the "standard"
approach to reading keys as they are hit, and this is the spec
implementors should follow when providing such a facility.

**HOWEVER**, support for control of buffering is implementation-defined,
and in fact I don't know of any system on which this works now.
