NAME [Toc] [Back]
term - format of compiled term file
SYNOPSIS [Toc] [Back]
term
DESCRIPTION [Toc] [Back]
Compiled terminfo descriptions are placed under the directory
/usr/share/lib/terminfo. In order to avoid a linear search of a huge
HP-UX system directory, a two-level scheme is used:
/usr/share/lib/terminfo/c/name where name is the name of the terminal,
and c is the first character of name. Thus, hp110 can be found in the
file /usr/share/lib/terminfo/h/hp110. Synonyms for the same terminal
are implemented by multiple links to the same compiled file.
The format has been chosen so that it is the same on all hardware. An
8-bit or longer byte is assumed, but no assumptions about byte
ordering or sign extension are made.
The compiled file is created using the tic program (see tic(1M)), and
read by the setupterm() routine. The file is divided into the
following six parts:
1. The header section begins the file and contains six short
integers in the following format:
1. Magic number (octal 0432);
2. Size, in bytes, of the names section;
3. Number of bytes in the Boolean section;
4. Number of short integers in the numbers section;
5. Number of offsets (short integers) in the strings
section;
6. Size, in bytes, of the string table.
Short integers are stored in two 8-bit bytes. The first
byte contains the least significant 8 bits of the value; the
second byte contains the most significant 8 bits. (Thus,
the value represented is 256*second+first.) The value -1 is
represented by 0377, 0377; other negative values are
illegal. The -1 generally means that a capability is
missing from this terminal. Note that this format
corresponds to the hardware of the VAX and PDP-11. Machines
where this does not correspond to the hardware read the
integers as two bytes and compute the result.
2. The terminal names section comes next. It contains the
first line of the terminfo description, listing the various
names for the terminal, separated by the | character. The
section is terminated with an ASCII NUL character.

3. In the Boolean section, the Boolean flags have one byte for
each flag. This byte is either 0 or 1 as the flag is absent
or present, respectively. The capabilities are in the same
order as they are listed in the file <term.h>.
Between the Boolean section and the number section, a null
byte will be inserted, if necessary, to ensure that the
number section begins on an even byte. All short integers
are aligned on a short word boundary.
4. The numbers section is similar to the flags section. Each
capability consists of two bytes, and is stored as a short
integer. If the value represented is -1, the capability is
considered missing.
5. The strings section is also similar. Each capability is
stored as a short integer in the format above. A value of
-1 means the capability is missing. Otherwise, the value is
taken as an offset from the beginning of the string table.
Special characters in ^X or \c notation are stored in their
interpreted form, not the printing representation. Padding
information $nn and parameter information %x are stored
intact in uninterpreted form.
6. The final section is the string table. It contains all the
values of string capabilities referenced in the string
section. Each string is null terminated.
Note that it is possible for setupterm() to expect a different set of
capabilities than are actually present in the file. Either the
database might have been updated since setupterm() has been recompiled
(resulting in extra unrecognized entries in the file) or the program
may have been recompiled more recently than the database was updated
(resulting in missing entries). The routine setupterm() must be
prepared for both possibilities, which is why the numbers and sizes
are included. Also, new capabilities must always be added at the end
of the lists of Boolean, number, and string capabilities.

WARNINGS [Toc] [Back]
Total compiled entries cannot exceed 4096 bytes.
The name field cannot exceed 128 bytes.
Hewlett-Packard Company supports only those terminals that are listed
on the current list of supported devices. However, both non-supported
and supported terminals may be in the terminfo database. If nonsupported
terminals are used, they may not work correctly.
