fblocked - Test whether the last input operation exhausted all available input
fblocked channelId
The fblocked command returns 1 if the most recent input operation
on channelId returned less information than requested because all
available input was exhausted.
For example, if gets is invoked when there are only three
characters available for input and no end-of-line sequence, gets
returns an empty string and a subsequent call to fblocked will
return 1.
