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⌨️ 快捷键说明
