-<H2>DESCRIPTION</H2><PRE>
- These low-level routines must be called by programs that
- have to deal directly with the <STRONG>terminfo</STRONG> database to handle
- certain terminal capabilities, such as programming func-
- tion keys. For all other functionality, <STRONG>curses</STRONG> routines
- are more suitable and their use is recommended.
-
- Initially, <STRONG>setupterm</STRONG> should be called. Note that
- <STRONG>setupterm</STRONG> is automatically called by <STRONG>initscr</STRONG> and <STRONG>newterm</STRONG>.
- This defines the set of terminal-dependent variables
- [listed in <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG>]. The <STRONG>terminfo</STRONG> variables <STRONG>lines</STRONG> and
- <STRONG>columns</STRONG> are initialized by <STRONG>setupterm</STRONG> as follows: If
- <STRONG>use_env(FALSE)</STRONG> has been called, values for <STRONG>lines</STRONG> and
- <STRONG>columns</STRONG> specified in <STRONG>terminfo</STRONG> are used. Otherwise, if the
- environment variables <STRONG>LINES</STRONG> and <STRONG>COLUMNS</STRONG> exist, their val-
- ues 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 <STRONG>lines</STRONG> and <STRONG>columns</STRONG> specified in
- the <STRONG>terminfo</STRONG> database are used.
-
- The header files <STRONG>curses.h</STRONG> and <STRONG>term.h</STRONG> should be included
- (in this order) to get the definitions for these strings,
- numbers, and flags. Parameterized strings should be
- passed through <STRONG>tparm</STRONG> to instantiate them. All <STRONG>terminfo</STRONG>
- strings [including the output of <STRONG>tparm</STRONG>] should be printed
- with <STRONG>tputs</STRONG> or <STRONG>putp</STRONG>. Call the <STRONG>reset_shell_mode</STRONG> to restore
- <STRONG>enter_ca_mode</STRONG> upon startup and should output <STRONG>exit_ca_mode</STRONG>
- before exiting. Programs desiring shell escapes should
- call
-
- <STRONG>reset_shell_mode</STRONG> and output <STRONG>exit_ca_mode</STRONG> before the shell
- is called and should output <STRONG>enter_ca_mode</STRONG> and call
- <STRONG>reset_prog_mode</STRONG> after returning from the shell.
-
- The <STRONG>setupterm</STRONG> routine reads in the <STRONG>terminfo</STRONG> database, ini-
- tializing the <STRONG>terminfo</STRONG> structures, but does not set up the
- output virtualization structures used by <STRONG>curses</STRONG>. The ter-
- minal type is the character string <EM>term</EM>; if <EM>term</EM> is null,
- the environment variable <STRONG>TERM</STRONG> is used. All output is to
- file descriptor <STRONG>fildes</STRONG> which is initialized for output.
- If <EM>errret</EM> is not null, then <STRONG>setupterm</STRONG> returns <STRONG>OK</STRONG> or <STRONG>ERR</STRONG>
- and stores a status value in the integer pointed to by
- <EM>errret</EM>. A status of <STRONG>1</STRONG> in <EM>errret</EM> is normal, <STRONG>0</STRONG> means that
- the terminal could not be found, and <STRONG>-1</STRONG> means that the
- <STRONG>terminfo</STRONG> database could not be found. If <EM>errret</EM> is null,
- <STRONG>setupterm</STRONG> prints an error message upon finding an error
- and exits. Thus, the simplest call is:
-
- <STRONG>setupterm((char</STRONG> <STRONG>*)0,</STRONG> <STRONG>1,</STRONG> <STRONG>(int</STRONG> <STRONG>*)0);</STRONG>,
-
- which uses all the defaults and sends the output to <STRONG>std-</STRONG>
- <STRONG>out</STRONG>.
-
- The <STRONG>setterm</STRONG> routine is being replaced by <STRONG>setupterm</STRONG>. The
- call:
-
- <STRONG>setupterm(</STRONG><EM>term</EM><STRONG>,</STRONG> <STRONG>1,</STRONG> <STRONG>(int</STRONG> <STRONG>*)0)</STRONG>
-
- provides the same functionality as <STRONG>setterm(</STRONG><EM>term</EM><STRONG>)</STRONG>. The
- <STRONG>setterm</STRONG> routine is included here for BSD compatibility,
- and is not recommended for new programs.
-
- The <STRONG>set_curterm</STRONG> routine sets the variable <STRONG>cur_term</STRONG> to
- <EM>nterm</EM>, and makes all of the <STRONG>terminfo</STRONG> boolean, numeric, and
- string variables use the values from <EM>nterm</EM>. It returns
- the old value of <STRONG>cur_term</STRONG>.
-
- The <STRONG>del_curterm</STRONG> routine frees the space pointed to by
- <EM>oterm</EM> and makes it available for further use. If <EM>oterm</EM> is
- the same as <STRONG>cur_term</STRONG>, references to any of the <STRONG>terminfo</STRONG>
- boolean, numeric, and string variables thereafter may
- refer to invalid memory locations until another <STRONG>setupterm</STRONG>
- has been called.
-
- The <STRONG>restartterm</STRONG> routine is similar to <STRONG>setupterm</STRONG> and
- <STRONG>initscr</STRONG>, 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
- be different. Accordingly, it saves various tty state
- bits, does a setupterm, and then restores the bits.
-
- The <STRONG>tparm</STRONG> routine instantiates the string <EM>str</EM> with parame-
- ters <EM>pi</EM>. A pointer is returned to the result of <EM>str</EM> with
- the parameters applied.
-
- The <STRONG>tputs</STRONG> routine applies padding information to the
- string <EM>str</EM> and outputs it. The <EM>str</EM> must be a terminfo
- string variable or the return value from <STRONG>tparm</STRONG>, <STRONG>tgetstr</STRONG>,
- or <STRONG>tgoto</STRONG>. <EM>affcnt</EM> is the number of lines affected, or 1 if
- not applicable. <EM>putc</EM> is a <STRONG>putchar</STRONG>-like routine to which
- the characters are passed, one at a time.
-
- The <STRONG>putp</STRONG> routine calls <STRONG>tputs(</STRONG><EM>str</EM><STRONG>,</STRONG> <STRONG>1,</STRONG> <STRONG>putchar)</STRONG>. Note that
- the output of <STRONG>putp</STRONG> always goes to <STRONG>stdout</STRONG>, not to the
- <EM>fildes</EM> specified in <STRONG>setupterm</STRONG>.
-
- The <STRONG>vidputs</STRONG> routine displays the string on the terminal in
- the video attribute mode <EM>attrs</EM>, which is any combination
- of the attributes listed in <STRONG><A HREF="ncurses.3x.html">curses(3X)</A></STRONG>. The characters
- are passed to the <STRONG>putchar</STRONG>-like routine <EM>putc</EM>.
-
- The <STRONG>vidattr</STRONG> routine is like the <STRONG>vidputs</STRONG> routine, except
- that it outputs through <STRONG>putchar</STRONG>.
-
- The <STRONG>mvcur</STRONG> routine provides low-level cursor motion. It
- takes effect immediately (rather than at the next
- refresh).
-
- The <STRONG>tigetflag</STRONG>, <STRONG>tigetnum</STRONG> and <STRONG>tigetstr</STRONG> routines return the
- value of the capability corresponding to the <STRONG>terminfo</STRONG> <EM>cap-</EM>
- <EM>name</EM> passed to them, such as <STRONG>xenl</STRONG>.
-
- The <STRONG>tigetflag</STRONG> routine returns the value <STRONG>-1</STRONG> if <EM>capname</EM> is
- not a boolean capability, or <STRONG>0</STRONG> if it is cancelled or
- absent from the terminal description.
-
- The <STRONG>tigetnum</STRONG> routine returns the value <STRONG>-2</STRONG> if <EM>capname</EM> is
- not a numeric capability, or <STRONG>-1</STRONG> if it is cancelled or
- absent from the terminal description.
-
- The <STRONG>tigetstr</STRONG> routine returns the value <STRONG>(char</STRONG> <STRONG>*)-1</STRONG> if <EM>cap-</EM>
- <EM>name</EM> is not a string capability, or <STRONG>0</STRONG> if it is cancelled
- or absent from the terminal description.
-
- The <EM>capname</EM> for each capability is given in the table col-
- umn entitled <EM>capname</EM> code in the capabilities section of
- <STRONG><A HREF="terminfo.5.html">terminfo(5)</A></STRONG>.
-
- <STRONG>char</STRONG> <STRONG>*boolnames</STRONG>, <STRONG>*boolcodes</STRONG>, <STRONG>*boolfnames</STRONG>
-
-
- These null-terminated arrays contain the <EM>capnames</EM>, the
- <STRONG>termcap</STRONG> codes, and the full C names, for each of the <STRONG>ter-</STRONG>
- <STRONG>minfo</STRONG> variables.
-
-
-</PRE>
-<H2>RETURN VALUE</H2><PRE>
- Routines that return an integer return <STRONG>ERR</STRONG> upon failure
- and <STRONG>OK</STRONG> (SVr4 only specifies "an integer value other than
- <STRONG>ERR</STRONG>") upon successful completion, unless otherwise noted
- in the preceding routine descriptions.
-
- Routines that return pointers always return <STRONG>NULL</STRONG> on error.
-
-
-</PRE>
-<H2>NOTES</H2><PRE>
- The <STRONG>setupterm</STRONG> routine should be used in place of <STRONG>setterm</STRONG>.
- It may be useful when you want to test for terminal capa-
- bilities without committing to the allocation of storage
- involved in <STRONG>initscr</STRONG>.
-
- Note that <STRONG>vidattr</STRONG> and <STRONG>vidputs</STRONG> may be macros.
-
-
-</PRE>
-<H2>PORTABILITY</H2><PRE>
- The function <STRONG>setterm</STRONG> 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, <STRONG>set_curterm</STRONG> has an <STRONG>int</STRONG> return type
- and returns <STRONG>OK</STRONG> or <STRONG>ERR</STRONG>. We have chosen to implement the
- XSI Curses semantics.
-
- In System V Release 4, the third argument of <STRONG>tputs</STRONG> has the
- type <STRONG>int</STRONG> <STRONG>(*putc)(char)</STRONG>.
-
- The XSI Curses standard prototypes <STRONG>tparm</STRONG> with a fixed num-
- ber of parameters, rather than a variable argument list.
