NAME
term - format of compiled terminfo files
SYNOPSIS
/usr/lib/share/terminfo/?/*
DESCRIPTION
Compiled terminfo(4) description files are placed under the directory
/usr/share/lib/terminfo. In order to avoid a linear search of a huge
UNIX 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, 97801 can be found in the
file /usr/share/lib/terminfo/9/97801. 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 byte is assumed, but no assumptions about byte ordering or sign
extension are made. Thus, these binary terminfo files can be trans-
ported to other hardware with 8-bit bytes.
Short integers are stored in two 8-bit bytes. The first byte contains
the least significant 8 bits of the value, and the second byte con-
tains the most significant 8 bits. (Thus, the value represented is
256*second+first.) The value -1 is represented by 0377,0377, and the
value -2 is represented by 0376,0377; other negative values are ille-
gal. The -1 generally means that a capability is missing from this
terminal. The -2 means that the capability has been cancelled in the
terminfo source and also is to be considered missing.
The compiled file is created from the source file descriptions of the
terminals [see the -I option of infocmp(1M)] by using the terminfo
compiler, tic(1M), and read by the routine setupterm(3X). The file is
divided into six parts in the following order: the header, terminal
names, boolean flags, numbers, strings, and string table.
The header section begins the file. This section contains six short
integers in the format described below. These integers are:
1. the magic number (octal 0432);
2. the size, in bytes, of the names section;
3. the number of bytes in the boolean section;
4. the number of short integers in the numbers section;
5. the number of offsets (short integers) in the strings section;
6. the size, in bytes, of the string table.

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 bar (|) character [see termnames(5)]. The section is
terminated with an ASCII NUL character.
The boolean flags have one byte for each flag. This byte is either 0
or 1 as the flag is present or absent. The value of 2 means that the
flag has been cancelled. The capabilities are in the same order as the
file <term.h>.
Between the boolean section and the number section, a null byte is
inserted, if necessary, to ensure that the number section begins on an
even byte offset. All short integers are aligned on a short word boun-
dary.
The numbers section is similar to the boolean flags section. Each
capability takes up two bytes, and is stored as a short integer. If
the value represented is -1 or -2, the capability is taken to be miss-
ing.
The strings section is also similar. Each capability is stored as a
short integer, in the format above. A value of -1 or -2 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 repre-
sentation. Padding information ($<nn>) and parameter information (%x)
are stored intact in uninterpreted form.
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 data-
base may 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 - this 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.
