CAPTOINFO(1M-SysV)  RISC/os Reference Manual   CAPTOINFO(1M-SysV)



NAME
     captoinfo  - convert a termcap description into a terminfo
     description

SYNOPSIS
     captoinfo [-v ...]  [-V] [-1] [-w width] [ file ... ]

DESCRIPTION
     captoinfo looks in file for termcap descriptions.  For each
     one found, an equivalent terminfo(4) description is written
     to standard output, along with any comments found.  A
     description which is expressed as relative to another
     description (as specified in the termcap tc= field) will be
     reduced to the minimum superset before being output.

     If no file is given, then the environment variable TERMCAP
     is used for the filename or entry.  If TERMCAP is a full
     pathname to a file, only the terminal whose name is speci-
     fied in the environment variable TERM is extracted from that
     file.  If the environment variable TERMCAP is not set, then
     the file /etc/termcap is read.

     -v        print out tracing information on standard error as
               the program runs.  Specifying additional -v
               options will cause more detailed information to be
               printed.

     -V        print out the version of the program in use on
               standard error and exit.

     -1        cause the fields to print out one to a line.  Oth-
               erwise, the fields will be printed several to a
               line to a maximum width of 60 characters.

     -w        change the output to width characters.

FILES
     /usr/lib/terminfo/?/*         compiled terminal description
                                   database

CAVEATS
     Certain termcap defaults are assumed to be true.  For exam-
     ple, the bell character (terminfo bel) is assumed to be ^G.
     The linefeed capability (termcap nl) is assumed to be the
     same for both cursor_down and scroll_forward (terminfo cud1
     and ind, respectively.)  Padding information is assumed to
     belong at the end of the string.

     The algorithm used to expand parameterized information for
     termcap fields such as cursor_position (termcap cm, terminfo
     cup) will sometimes produce a string which, though techni-
     cally correct, may not be optimal.  In particular, the

     rarely used termcap operation %n will produce strings that
     are especially long.  Most occurrences of these non-optimal
     strings will be flagged with a warning message and may need
     to be recoded by hand.

     The short two-letter name at the beginning of the list of
     names in a termcap entry, a hold-over from an earlier ver-
     sion of the UNIX system, has been removed.

DIAGNOSTICS
     tgetent failed with return code n (reason).
               The termcap entry is not valid.  In particular,
               check for an invalid 'tc=' entry.

     unknown type given for the termcap code cc.
               The termcap description had an entry for cc whose
               type was not boolean, numeric or string.

cc.
     wrong type given for the boolean (numeric, string) termcap code
               The boolean termcap entry cc was entered as a
               numeric or string capability.

name.
     the boolean (numeric, string) termcap code cc is not a valid
               An unknown termcap code was specified.

     tgetent failed on TERM=term.
               The terminal type specified could not be found in
               the termcap file.

     TERM=term: cap cc (info ii) is NULL: REMOVED
               The termcap code was specified as a null string.
               The correct way to cancel an entry is with an '@',
               as in ':bs@:'.  Giving a null string could cause
               incorrect assumptions to be made by the software
               which uses termcap or terminfo.

vv.
     a function key for cc was specified, but it already has the value
               When parsing the ko capability, the key cc was
               specified as having the same value as the capabil-
               ity cc, but the key cc already had a value
               assigned to it.

bility.
     the unknown termcap name cc was specified in the ko termcap capa-
               A key was specified in the ko capability which
               could not be handled.

     the vi character v (info ii) has the value xx, but ma gives n.
               The ma capability specified a function key with a

CAPTOINFO(1M-SysV)  RISC/os Reference Manual   CAPTOINFO(1M-SysV)



               value different from that specified in another
               setting of the same key.

     the unknown vi key v was specified in the ma termcap capability.
               A vi(1) key unknown to captoinfo was specified in
               the ma capability.

values.
     Warning: termcap sg (nn) and termcap ug (nn) had different
               terminfo assumes that the sg (now xmc) and ug
               values were the same.

     Warning: the string produced for ii may be inefficient.
               The parameterized string being created should be
               rewritten by hand.

     Null termname given.
               The terminal type was null.  This is given if the
               environment variable TERM is not set or is null.

     cannot open file for reading.
               The specified file could not be opened.

NOTES
     captoinfo should be used to convert termcap entries to ter-
     minfo(4) entries because the termcap database (from earlier
     versions of UNIX System V) may not be supplied in future
     releases.
