They are some post-4.1 versions of System V curses, e.g., Solaris 2.5 and IRIX 6.x. The <STRONG>ncurses</STRONG> termcap names for them are invented; according to the XSI Curses standard, they have no termcap names.

Comments may be included on lines beginning with ``#''. Capabilities in <EM>terminfo</EM> are of three types: Boolean capa- bilities which indicate that the terminal has some particular feature, numeric capabilities giving the size of the terminal or the size of particular delays, and string capabilities, which give a sequence which can be used to perform particular terminal operations. <STRONG>Types</STRONG> <STRONG>of</STRONG> <STRONG>Capabilities</STRONG> All capabilities have names. For instance, the fact that ANSI-standard terminals have <EM>automatic</EM> <EM>margins</EM> (i.e., an automatic return and line-feed when the end of a line is reached) is indicated by the capability <STRONG>am</STRONG>. Hence the description of ansi includes <STRONG>am</STRONG>. Numeric capabilities are followed by the character `#' and then a positive value. Thus <STRONG>cols</STRONG>, which indicates the number of columns the ter- minal has, gives the value `80' for ansi. Values for numeric capabilities may be specified in decimal, octal or hexadecimal, using the C programming language conventions (e.g., 255, 0377 and 0xff or 0xFF). Finally, string valued capabilities, such as <STRONG>el</STRONG> (clear to end of line sequence) are given by the two-character code, an `=', and then a string ending at the next following `,'. A number of escape sequences are provided in the string valued capabilities for easy encoding of characters there. Both <STRONG>\E</STRONG> and <STRONG>\e</STRONG> map to an ESCAPE character, <STRONG>^x</STRONG> maps to a control-x for any appropriate x, and the sequences <STRONG>\n</STRONG> <STRONG>\l</STRONG> <STRONG>\r</STRONG> <STRONG>\t</STRONG> <STRONG>\b</STRONG> <STRONG>\f</STRONG> <STRONG>\s</STRONG> give a newline, line-feed, return, tab, backspace, form-feed, and space. Other escapes include <STRONG>\^</STRONG> for <STRONG>^</STRONG>, <STRONG>\\</STRONG> for <STRONG>\</STRONG>, <STRONG>\</STRONG>, for comma, <STRONG>\:</STRONG> for <STRONG>:</STRONG>, and <STRONG>\0</STRONG> for null. (<STRONG>\0</STRONG> will produce \200, which does not terminate a string but behaves as a null character on most terminals, provid- ing CS7 is specified. See <STRONG><A HREF="stty.1.html">stty(1)</A></STRONG>.) Finally, characters may be given as three octal digits after a <STRONG>\</STRONG>. A delay in milliseconds may appear anywhere in a string capability, enclosed in $<..> brackets, as in <STRONG>el</STRONG>=\EK$<5>, and padding characters are supplied by <EM>tputs</EM> to provide this delay. The delay must be a number with at most one decimal place of precision; it may be followed by suffixes `*' or '/' or both. A `*' indicates that the padding required is proportional to the number of lines affected by the operation, and the amount given is the per- affected-unit padding required. (In the case of insert character, the factor is still the number of <EM>lines</EM> affected.) Normally, padding is advisory if the device has the <STRONG>xon</STRONG> capability; it is used for cost computation but does not trigger delays. A `/' suffix indicates that the padding is mandatory and forces a delay of the given number of milliseconds even on devices for which <STRONG>xon</STRONG> is present to indicate flow control. Sometimes individual capabilities must be commented out. To do this, put a period before the capability name. For example, see the second <STRONG>ind</STRONG> in the example above. <STRONG>Fetching</STRONG> <STRONG>Compiled</STRONG> <STRONG>Descriptions</STRONG> If the environment variable TERMINFO is set, it is inter- preted as the pathname of a directory containing the com- piled description you are working on. Only that directory is searched. If TERMINFO is not set, the <STRONG>ncurses</STRONG> version of the ter- minfo reader code will instead look in the directory <STRONG>$HOME/.terminfo</STRONG> for a compiled description. If it fails to find one there, and the environment variable TER- MINFO_DIRS is set, it will interpret the contents of that variable as a list of colon- separated directories to be searched (an empty entry is interpreted as a command to search <EM>/usr/share/terminfo</EM>). If no description is found in any of the TERMINFO_DIRS directories, the fetch fails. If neither TERMINFO nor TERMINFO_DIRS is set, the last place tried will be the system terminfo directory, <EM>/usr/share/terminfo</EM>. (Neither the <STRONG>$HOME/.terminfo</STRONG> lookups nor TERMINFO_DIRS extensions are supported under stock System V ter- minfo/curses.) <STRONG>Preparing</STRONG> <STRONG>Descriptions</STRONG> We now outline how to prepare descriptions of terminals.
