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



_________________________________________________________________

NAME
     fblocked - Test whether the last input  operation  exhausted
     all available input

SYNOPSIS
     fblocked _c_h_a_n_n_e_l_I_d
_________________________________________________________________


DESCRIPTION
     The fblocked command returns 1  if  the  most  recent  input
     operation   on  _c_h_a_n_n_e_l_I_d  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.
