DESCRIPTION

     These functions extract and use capabilities from a terminal capability database, usually /usr/share/misc/terminfo, the format of which is
     described in terminfo(5).	These are low level routines; see curses(3) for a higher level package.

     The setupterm() function extracts the entry for terminal name and then calls set_curterm() to set cur_term to it.	If name is NULL then it is
     replaced by the environment variable TERM.  The setupterm() function returns 0 on success and -1 on error.  errret is set to -1 if the
     terminfo database could not be opened, 0 if the terminal could not be found in the database, and 1 if all went well.

     The set_curterm() function sets the variable cur_term to nterm and makes all of the terminfo boolean, numeric and string variables use the
     values from nterm.  The global variables PC and ospeed are then set.  The old value of cur_term is returned.  The del_curterm() function
     frees space pointed to by oterm.

     The termname() function returns the name of cur_term.  The longname() function returns the description of cur_term.

     The tigetflag() function gets the boolean value of capability id, returning -1 if it is not a valid capability.  The tigetnum() function gets
     the numeric value of the capability id, returning -2 if it is not a valid capability.  The tigetstr() function returns the string value of
     the capability id, returning (char *)-1 if it is not a valid capability.

     The tparm() function returns a string decoded from cm with the parameters p1 ...  p9 applied.  Some capabilities require string parameters
     and only platforms that can fit a char * pointer inside a long can use them.  For platforms which don't support this, NULL is returned and
     errno is set to ENOTSUPP.	The string encoding and parameter application is described in terminfo(5).

     The tputs() function applies padding information to the string cp; affcnt gives the number of lines affected by the operation, or 1 if this
     is not applicable; outc is a function which is called by each character in turn.  The external variable ospeed controls how many padding
     characters are sent in relation to the terminal speed.  The putp() function calls tputs(str, 1, putchar).	The output from putp() always goes
     to stdout.

   NetBSD Extensions To Terminfo
     The tiparm() function allows variadic parameters instead of 9 fixed longs.  Numeric parameters must be passed as int.  String parameters must
     be passed as char * and works on all platforms, unlike tparm().

     The ti_*() functions correspond to the standard t*() functions but take an additional TERMINAL * parameter so that the terminal can be speci-
     fied instead of assuming cur_term.  These functions use private variables to the TERMINAL instead of the global variables, such as PC and
     ospeed.
