fblocked(n)                                 Tcl Built-In Commands                                fblocked(n)

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 informa-tion information
       tion 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.

       ChannelId must be an identifier for an open channel such as a Tcl standard channel (stdin, stdout, or |
       stderr),  the  return value from an invocation of open or socket, or the result of a channel creation |
       command provided by a Tcl extension.
