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.
