NAME
fblocked - Test whether the last input operation exhausted
all available input
SYNOPSIS
fblocked channelId
_________________________________________________________________
DESCRIPTION
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.
