+
+   <STRONG>User-Defined</STRONG> <STRONG>Capabilities</STRONG>
+       The preceding section listed the <EM>predefined</EM>  capabilities.
+       They  deal  with  some  special  features for terminals no
+       longer (or possibly never) produced.   Occasionally  there
+       are  special features of newer terminals which are awkward
+       or impossible to represent by reusing the predefined capa-
+       bilities.
+
+       <STRONG>ncurses</STRONG> addresses this limitation by allowing user-defined
+       capabilities.  The <STRONG>tic</STRONG> and <STRONG>infocmp</STRONG> programs provide the <STRONG>-x</STRONG>
+       option  for  this  purpose.   When  <STRONG>-x</STRONG>  is set, <STRONG>tic</STRONG> treats
+       unknown capabilities as user-defined.   That  is,  if  <STRONG>tic</STRONG>
+       encounters  a capability name which it does not recognize,
+       it infers its type (boolean, number or  string)  from  the
+       syntax and makes an extended table entry for that capabil-
+       ity.  The <STRONG>use_extended_names</STRONG> function makes this  informa-
+       tion conditionally available to applications.  The ncurses
+       library provides the data leaving most of the behavior  to
+       applications:
+
+       <STRONG>o</STRONG>   User-defined capability strings whose name begins with
+           "k" are treated as function keys.
+
+       <STRONG>o</STRONG>   The types (boolean, number, string) determined by  <STRONG>tic</STRONG>
+           can be inferred by successful calls on <STRONG>tigetflag</STRONG>, etc.
+
+       <STRONG>o</STRONG>   If  the  capability name happens to be two characters,
+           the capability is also available through  the  termcap
+           interface.
+
+       While termcap is said to be extensible because it does not
+       use a predefined set of capabilities, in practice  it  has
+       been  limited  to  the  capabilities  defined  by terminfo
+       implementations.  As  a  rule,  user-defined  capabilities
+       intended for use by termcap applications should be limited
+       to booleans and numbers to avoid  running  past  the  1023
+       byte  limit  assumed  by termcap implementations and their
+       applications.  In particular, providing extended  sets  of
+       function  keys  (past the 60 numbered keys and the handful
+       of special named keys) is best done using the longer names
+       available using terminfo.

        is searching for is, several bad things can happen.
 
-       Some termcap libraries print a warning message or exit  if

        application programs allocate more than the recommended 1K
        for the termcap entry; others do not.
 
        Each termcap entry has two important sizes associated with
        it: before "tc" expansion, and after "tc" expansion.  "tc"
-       is the capability that tacks on another termcap  entry  to
-       the  end  of  the current one, to add on its capabilities.
-       If a termcap entry does not use the "tc" capability,  then

+       the end of the current one, to add  on  its  capabilities.
+       If  a termcap entry does not use the "tc" capability, then
        of course the two lengths are the same.
 
-       The  "before  tc  expansion"  length is the most important
-       one, because it affects more than just users of that  par-

        exists in /etc/termcap, minus the backslash-newline pairs,
        which <STRONG>tgetent()</STRONG> strips out while reading it.  Some termcap

+       libraries  strip  off  the final newline, too (GNU termcap

-       *    a  termcap  entry  before expansion is more than 1023
-            bytes long,
-
-       *    and the application has only allocated a 1k buffer,
-
-       *    and the termcap library (like the one in  BSD/OS  1.1
-            and  GNU)  reads  the whole entry into the buffer, no

-            wants,
-
-       *    and  <STRONG>tgetent()</STRONG>  is searching for a terminal type that
-            either is the long entry, appears in the termcap file
-            after  the long entry, or does not appear in the file
-            at all (so that <STRONG>tgetent()</STRONG> has  to  search  the  whole

-
-       Then  <STRONG>tgetent()</STRONG>  will overwrite memory, perhaps its stack,

        In summary, a termcap entry that is longer than 1023 bytes
