[ros-kernel] ReadConsoleA() and getc()

[Jason F. <jas...@ya...>]

Ok I just want to ask a question to clear things up:

If you tell ReadConsoleA to only read 1 character, will it return
upon reading that one characer - even if it's in line mode? Or must
you press enter, even though you only asked for 1?

getc() only returns one character, so reading in an entire line is
useless.

Thanks
- Jason

IIRC ReadConsole will return only when a complete line is available 
(in ENABLE_LINE_INPUT mode) but only as many characters as asked for will
be returned. Any remaining characters will be buffered internally.
