NAME
fblocked - Test whether the last input operation exhausted all avail-
able 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 avail-
able 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.
