/* This file contains functions which simulate the termcap functions.
|
|
*
|
|
* It doesn't access a "termcap" file. Instead, it uses an initialized array
|
|
* of strings to store the entries. Any string that doesn't start with a ':'
|
|
* is taken to be the name of a type of terminal. Any string that does start
|
|
* with a ':' is interpretted as the list of fields describing all of the
|
|
* terminal types that precede it.
|
|
*
|
|
* Note: since these are C strings, you can't use special sequences like
|
|
* ^M or \E in the fields; your C compiler won't understand them. Also,
|
|
* at run time there is no way to tell the difference between ':' and '\072'
|
|
* so I sure hope your terminal definition doesn't require a ':' character.
|
|
*
|
|
* getenv(TERM) on VMS checks the SET TERM device setting. To implement
|
|
* non-standard terminals set the logical ELVIS_TERM in VMS. (jdc)
|
|
*
|
|
* Other possible terminal types are...
|
|
* TERM_WYSE925 - "wyse925", a Wyse 50 terminal emulating Televideo 925
|
|
* ... or you could set $TERMCAP to the terminal's description string, which
|
|
* $TERM set up to match it.
|
|
*
|
|
* Note that you can include several terminal types at the same time. Elvis
|
|
* chooses which entry to use at runtime, based primarily on the value of $TERM.
