This value generally -means that the corresponding capability is missing from this terminal. -Note that this format corresponds to the hardware of the \s-1VAX\s+1 -and \s-1PDP\s+1-11 (that is, little-endian machines). -Machines where this does not correspond to the hardware must read the -integers as two bytes and compute the little-endian value. -.PP -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 \s-1ASCII NUL\s+1 character. -.PP -The boolean flags have one byte for each flag. -This byte is either 0 or 1 as the flag is present or absent. -The capabilities are in the same order as the file <term.h>. -.PP -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 (this is a -relic of the PDP-11's word-addressed architecture, originally -designed in to avoid IOT traps induced by addressing a word on an -odd byte boundary). -All short integers are aligned on a short word boundary. -.PP -The numbers section is similar to the flags section. -Each capability takes up two bytes, -and is stored as a little-endian short integer. -If the value represented is \-1, the capability is taken to be missing. -.PP -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 \ec notation are stored in their -interpreted form, not the printing representation. -Padding information $<nn> and parameter information %x are -stored intact in uninterpreted form. -.PP -The final section is the string table. -It contains all the values of string capabilities referenced in -the string section. -Each string is null terminated. -.PP -Note that it is possible for -.I setupterm -to expect a different set of capabilities -than are actually present in the file. -Either the database may have been updated since -.I setupterm -has been recompiled -(resulting in extra unrecognized entries in the file) -or the program may have been recompiled more recently -than the database was updated -(resulting in missing entries). -The routine -.I setupterm -must be prepared for both possibilities \- -this is why the numbers and sizes are included. -Also, new capabilities must always be added at the end of the lists -of boolean, number, and string capabilities. -.PP -Despite the consistent use of little-endian for numbers and the otherwise -self-describing format, it is not wise to count on portability of binary -terminfo entries between commercial UNIX versions. The problem is that there -are at least three versions of terminfo (under HP-UX, AIX, and OSF/1) which -diverged from System V terminfo after SVr1, and have added extension -capabilities to the string table that (in the binary format) collide with -System V and XSI Curses extensions. See \fBterminfo\fR(\*n) for detailed -discussion of terminfo source compatibility issues. -.PP -As an example, here is a hex dump of the description for the Lear-Siegler -ADM-3, a popular though rather stupid early terminal: -.nf -.sp -adm3a|lsi adm3a, - am, - cols#80, lines#24, - bel=^G, clear=\032$<1>, cr=^M, cub1=^H, cud1=^J, - cuf1=^L, cup=\\E=%p1%{32}%+%c%p2%{32}%+%c, cuu1=^K, - home=^^, ind=^J, -.sp -.ft CW -\s-20000 1a 01 10 00 02 00 03 00 82 00 31 00 61 64 6d 33 ........ ..1.adm3 -0010 61 7c 6c 73 69 20 61 64 6d 33 61 00 00 01 50 00 a|lsi ad m3a...P. -0020 ff ff 18 00 ff ff 00 00 02 00 ff ff ff ff 04 00 ........ ........ -0030 ff ff ff ff ff ff ff ff 0a 00 25 00 27 00 ff ff ........ ..%.'... -0040 29 00 ff ff ff ff 2b 00 ff ff 2d 00 ff ff ff ff ).....+. ..-..... -0050 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ........ ........ -0060 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ........ ........ -0070 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ........ ........ -0080 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ........ ........ -0090 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ........ ........ -00a0 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ........ ........ -00b0 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ........ ........ -00c0 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ........ ........ -00d0 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ........ ........ -00e0 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ........ ........ -00f0 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ........ ........ -0100 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ........ ........ -0110 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ........ ........ -0120 ff ff ff ff ff ff 2f 00 07 00 0d 00 1a 24 3c 31 ....../. .....$<1 -0130 3e 00 1b 3d 25 70 31 25 7b 33 32 7d 25 2b 25 63 >..=%p1% {32}%+%c -0140 25 70 32 25 7b 33 32 7d 25 2b 25 63 00 0a 00 1e %p2%{32} %+%c.... -0150 00 08 00 0c 00 0b 00 0a 00 ........ .\s+2 -.ft R -.fi -.sp -.PP -Some limitations: total compiled entries cannot exceed 4096 bytes. -The name field cannot exceed 128 bytes. -.SH FILES -\*d/*/* compiled terminal capability data base -.SH SEE ALSO -\fBcurses\fR(3X), \fBterminfo\fR(\*n). -.\"# -.\"# The following sets edit modes for GNU EMACS -.\"# Local Variables: -.\"# mode:nroff -.\"# fill-column:79 -.\"# End: |
