@ -73,18 +73,17 @@ The @dfn{terminal input queue} is also sometimes referred to as its
@dfn{typeahead buffer}. It holds the characters that have been received
from the terminal but not yet read by any process.
The size of the terminal's input queue is described by the
@code{MAX_INPUT} and @w{@code{_POSIX_MAX_INPUT}} parameters; see @ref{Limits
for Files}. You are guaranteed a queue size of at least
@code{MAX_INPUT}, but the queue might be larger, and might even
dynamically change size. If input flow control is enabled by setting
the @code{IXOFF} input mode bit (@pxref{Input Modes}), the terminal
driver transmits STOP and START characters to the terminal when
necessary to prevent the queue from overflowing. Otherwise, input may
be lost if it comes in too fast from the terminal. In canonical mode,
all input stays in the queue until a newline character is received, so
the terminal input queue can fill up when you type a very long line.
