+<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
+ the tty modes before exiting [see <STRONG><A HREF="curs_kernel.3x.html">curs_kernel(3x)</A></STRONG>]. Pro-
+ grams which use cursor addressing should output
+ <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 return value of <STRONG>OK</STRONG> combined with status of <STRONG>1</STRONG> in
+ <EM>errret</EM> is normal. If <STRONG>ERR</STRONG> is returned, examine <EM>errret</EM>:
+
+ <STRONG>1</STRONG> means that the terminal is hardcopy, cannot be
+ used for curses applications.
+
+ <STRONG>0</STRONG> means that the terminal could not be found, or
+ that it is a generic type, having too little
+ information for curses applications to run.
+
+ <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
+ and the input and output options are the same as when mem-
+ ory 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 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>vid_attr</STRONG> and <STRONG>vid_puts</STRONG> 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 <STRONG>vid_attr</STRONG> and <STRONG>vid_puts</STRONG> routines
+ are designed to use the attribute constants with the <EM>WA</EM><STRONG>_</STRONG>
+ prefix. The opts argument is reserved for future use.
+ Currently, applications must provide a null pointer for
+ that argument.
+
+ 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>capname</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 canceled 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 canceled 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 canceled 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>
+
+ <STRONG>char</STRONG> <STRONG>*numnames</STRONG>, <STRONG>*numcodes</STRONG>, <STRONG>*numfnames</STRONG>
+
+ <STRONG>char</STRONG> <STRONG>*strnames</STRONG>, <STRONG>*strcodes</STRONG>, <STRONG>*strfnames</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.
+ This implementation uses a variable argument list.
+ Portable applications should provide 9 parameters after
+ the format; zeroes are fine for this purpose.
+
+ XSI notes that after calling <STRONG>mvcur</STRONG>, the curses state may
+ not match the actual terminal state, and that an applica-
+ tion should touch and refresh the window before resuming
+ normal curses calls. Both ncurses and System V Release 4
+ curses implement <STRONG>mvcur</STRONG> using the SCREEN data allocated in
+ either <STRONG>initscr</STRONG> or <STRONG>newterm</STRONG>. So though it is documented as
+ a terminfo function, <STRONG>mvcur</STRONG> is really a curses function
+ which is not well specified.
