** The format of compiled terminfo files is as follows:

**
|
||
|
** Header (12 bytes), containing information given below
|
||
|
** Names Section, containing the names of the terminal
|
||
|
** Boolean Section, containing the values of all of the
|
||
|
** boolean capabilities
|
||
|
** A null byte may be inserted here to make
|
||
|
** sure that the Number Section begins on an
|
||
|
** even word boundary.
|
||
|
** Number Section, containing the values of all of the numeric
|
||
|
** capabilities, each as a short integer
|
||
|
** String Section, containing short integer offsets into the
|
||
|
** String Table, one per string capability
|
||
|
** String Table, containing the actual characters of the string
|
||
|
** capabilities.
|
||
|
**
|
||
|
** NOTE that all short integers in the file are stored using VAX/PDP-style
|
||
|
** byte-order, i.e., least-significant byte first.
|
||
|
**
|
||
|
** There is no structure definition here because it would only confuse
|
||
|
** matters. Terminfo format is a raw byte layout, not a structure
|
||
|
** dump. If you happen to be on a little-endian machine with 16-bit
|
||
|
** shorts that requires no padding between short members in a struct,
|
||
|
** then there is a natural C structure that captures the header, but
|
||
|
** not very helpfully.
