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.
