tcl7.6 User Commands - fblocked
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 char-
acters available for input and no end-of-line sequence, gets
returns an empty string and a subsequent call to fblocked
will return 1.
