   8 '\" The definitions below are for supplemental macros used in Tcl/Tk
   9 '\" manual entries.
  10 '\"
  11 '\" .AP type name in/out ?indent?
  12 '\"     Start paragraph describing an argument to a library procedure.
  13 '\"     type is type of argument (int, etc.), in/out is either "in", "out",
  14 '\"     or "in/out" to describe whether procedure reads or modifies arg,
  15 '\"     and indent is equivalent to second arg of .IP (shouldn't ever be
  16 '\"     needed;  use .AS below instead)
  17 '\"
  18 '\" .AS ?type? ?name?
  19 '\"     Give maximum sizes of arguments for setting tab stops.  Type and
  20 '\"     name are examples of largest possible arguments that will be passed
  21 '\"     to .AP later.  If args are omitted, default tab stops are used.
  22 '\"
  23 '\" .BS
  24 '\"     Start box enclosure.  From here until next .BE, everything will be
  25 '\"     enclosed in one large box.
  26 '\"
  27 '\" .BE
  28 '\"     End of box enclosure.
  29 '\"
  30 '\" .CS
  31 '\"     Begin code excerpt.
  32 '\"
  33 '\" .CE
  34 '\"     End code excerpt.
  35 '\"
  36 '\" .VS ?version? ?br?
  37 '\"     Begin vertical sidebar, for use in marking newly-changed parts
  38 '\"     of man pages.  The first argument is ignored and used for recording
  39 '\"     the version when the .VS was added, so that the sidebars can be
  40 '\"     found and removed when they reach a certain age.  If another argument
  41 '\"     is present, then a line break is forced before starting the sidebar.
  42 '\"
  43 '\" .VE
  44 '\"     End of vertical sidebar.
  45 '\"
  46 '\" .DS
  47 '\"     Begin an indented unfilled display.
  48 '\"
  49 '\" .DE
  50 '\"     End of indented unfilled display.
  51 '\"
  52 '\" .SO
  53 '\"     Start of list of standard options for a Tk widget.  The
  54 '\"     options follow on successive lines, in four columns separated
  55 '\"     by tabs.
  56 '\"
  57 '\" .SE
  58 '\"     End of list of standard options for a Tk widget.
  59 '\"
  60 '\" .OP cmdName dbName dbClass
  61 '\"     Start of description of a specific option.  cmdName gives the
  62 '\"     option's name as specified in the class command, dbName gives
  63 '\"     the option's name in the option database, and dbClass gives
  64 '\"     the option's class in the option database.
  65 '\"
  66 '\" .UL arg1 arg2
  67 '\"     Print arg1 underlined, then print arg2 normally.

 248 fblocked \- Test whether the last input operation exhausted all available input
 249 .SH SYNOPSIS
 250 \fBfblocked \fIchannelId\fR
 251 .BE
 252
 253 .SH DESCRIPTION
 254 .PP
 255 The \fBfblocked\fR command returns 1 if the most recent input operation
 256 on \fIchannelId\fR returned less information than requested because all
 257 available input was exhausted.
 258 For example, if \fBgets\fR is invoked when there are only three
 259 characters available for input and no end-of-line sequence, \fBgets\fR
 260 returns an empty string and a subsequent call to \fBfblocked\fR will
 261 return 1.
