       These  low-level  routines  must be called by programs that have to deal directly with the
       terminfo database to handle certain terminal capabilities, such	as  programming  function
       keys.   For  all  other	functionality, curses routines are more suitable and their use is

       Initially, setupterm should be called.  Note that setupterm  is	automatically  called  by
       initscr and newterm.  This defines the set of terminal-dependent variables [listed in ter-
       minfo(5)].  The terminfo variables lines and columns are initialized by setupterm as  fol-
       lows:  If  use_env(FALSE)  has been called, values for lines and columns specified in ter-
       minfo are used.	Otherwise, if the environment variables LINES and  COLUMNS  exist,  their
       values  are  used.  If these environment variables do not exist and the program is running
       in a window, the current window size is used.  Otherwise, if the environment variables  do
       not exist, the values for lines and columns specified in the terminfo database are used.

       The header files curses.h and term.h should be included (in this order) to get the defini-
       tions for these strings, numbers, and  flags.   Parameterized  strings  should  be  passed
       through	tparm  to instantiate them.  All terminfo strings [including the output of tparm]
       should be printed with tputs or putp.  Call the reset_shell_mode to restore the tty  modes
       before  exiting [see curs_kernel(3X)].  Programs which use cursor addressing should output
       enter_ca_mode upon startup and should output exit_ca_mode before exiting.  Programs desir-
       ing shell escapes should call

       reset_shell_mode  and  output  exit_ca_mode  before  the shell is called and should output
       enter_ca_mode and call reset_prog_mode after returning from the shell.

       The setupterm routine reads in the terminfo database,  initializing  the  terminfo  struc-
       tures,  but does not set up the output virtualization structures used by curses.  The ter-
       minal type is the character string term; if term is null, the environment variable TERM is
       used.  All output is to file descriptor fildes which is initialized for output.	If errret
       is not null, then setupterm returns OK or ERR and stores a status  value  in  the  integer
       pointed to by errret.  A return value of OK combined with status of 1 in errret is normal.
       If ERR is returned, examine errret:

	      1    means that the terminal is hardcopy, cannot be used for curses applications.

	      0    means that the terminal could not be found, or that it is a generic type, hav-
		   ing too little information for curses applications to run.

	      -1   means that the terminfo database could not be found.

       If  errret  is  null,  setupterm  prints an error message upon finding an error and exits.
       Thus, the simplest call is:

	     setupterm((char *)0, 1, (int *)0);,

       which uses all the defaults and sends the output to stdout.

       The setterm routine is being replaced by setupterm.  The call:

	     setupterm(term, 1, (int *)0)

       provides the same functionality as setterm(term).  The setterm routine  is  included  here
       for BSD compatibility, and is not recommended for new programs.

       The set_curterm routine sets the variable cur_term to nterm, and makes all of the terminfo
       boolean, numeric, and string variables use the values from  nterm.   It	returns  the  old
       value of cur_term.

       The  del_curterm  routine  frees  the space pointed to by oterm and makes it available for
       further use.  If oterm is the same as cur_term, references to any of the terminfo boolean,
       numeric,  and  string  variables  thereafter  may  refer to invalid memory locations until
       another setupterm has been called.

       The restartterm routine is similar to setupterm and initscr,  except  that  it  is  called
       after  restoring memory to a previous state (for example, when reloading a game saved as a
       core image dump).  It assumes that the windows and the input and output	options  are  the
       same  as  when  memory  was  saved,  but the terminal type and baud rate may be different.
       Accordingly, it saves various tty state bits, does a  setupterm,  and  then  restores  the

       The  tparm  routine instantiates the string str with parameters pi.  A pointer is returned
       to the result of str with the parameters applied.

       The tputs routine applies padding information to the string str and outputs it.	 The  str
       must  be  a  terminfo  string  variable or the return value from tparm, tgetstr, or tgoto.
       affcnt is the number of lines affected, or 1 if not applicable.	putc  is  a  putchar-like
       routine to which the characters are passed, one at a time.

       The  putp  routine calls tputs(str, 1, putchar).  Note that the output of putp always goes
       to stdout, not to the fildes specified in setupterm.

       The vidputs routine displays the string on the terminal in the video attribute mode attrs,
       which  is  any  combination  of	the  attributes listed in curses(3X).  The characters are
       passed to the putchar-like routine putc.

       The vidattr routine is like the vidputs routine, except that it outputs through putchar.

       The vid_attr and vid_puts routines correspond to vidattr and vidputs, respectively.   They
       use a set of arguments for representing the video attributes plus color, i.e., one of type
       attr_t for the attributes and one of short for the color_pair number.   The  vid_attr  and
       vid_puts  routines  are	designed to use the attribute constants with the WA_ prefix.  The
       opts argument is reserved for future use.  Currently, applications  must  provide  a  null
       pointer for that argument.

       The  mvcur  routine provides low-level cursor motion.  It takes effect immediately (rather
       than at the next refresh).

       The tigetflag, tigetnum and tigetstr routines return the value of  the  capability  corre-
       sponding to the terminfo capname passed to them, such as xenl.

       The tigetflag routine returns the value -1 if capname is not a boolean capability, or 0 if
       it is canceled or absent from the terminal description.

       The tigetnum routine returns the value -2 if capname is not a numeric capability, or -1 if
       it is canceled or absent from the terminal description.

       The  tigetstr  routine returns the value (char *)-1 if capname is not a string capability,
       or 0 if it is canceled or absent from the terminal description.

       The capname for each capability is given in the table column entitled capname code in  the
       capabilities section of terminfo(5).

       char *boolnames, *boolcodes, *boolfnames

       char *numnames, *numcodes, *numfnames

       char *strnames, *strcodes, *strfnames

       These  null-terminated  arrays  contain	the  capnames,	the termcap codes, and the full C
       names, for each of the terminfo variables.

       Routines that return an integer return ERR upon failure and OK (SVr4  only  specifies  "an
       integer	value  other than ERR") upon successful completion, unless otherwise noted in the
       preceding routine descriptions.

       Routines that return pointers always return NULL on error.

       The setupterm routine should be used in place of setterm.  It may be useful when you  want
       to test for terminal capabilities without committing to the allocation of storage involved
       in initscr.

       Note that vidattr and vidputs may be macros.

       The function setterm is not described in the XSI Curses standard and  must  be  considered
       non-portable.  All other functions are as described in the XSI curses standard.

       In  System V Release 4, set_curterm has an int return type and returns OK or ERR.  We have
       chosen to implement the XSI Curses semantics.

       In System V Release 4, the third argument of tputs has the type int (*putc)(char).

       The XSI Curses standard prototypes tparm with a fixed number of parameters, rather than	a
       variable  argument  list.   This  implementation  uses a variable argument list.  Portable
       applications should provide 9 parameters after the format; zeroes are fine for  this  pur-

       XSI  notes  that  after	calling mvcur, the curses state may not match the actual terminal
       state, and that an application should touch and refresh the window before resuming  normal
       curses calls.  Both ncurses and System V Release 4 curses implement mvcur using the SCREEN
       data allocated in either initscr or newterm.  So though it is  documented  as  a  terminfo
       function, mvcur is really a curses function which is not well specified.
