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 subse- quent call to fblocked will return 1.
