This is done automatically by initscr(). - - reset_prog_mode() and reset_shell_mode() restore the terminal to - "program" (in curses) or "shell" (not in curses) state. These - are done automatically by endwin() and doupdate() after an - endwin(), so they would normally not be called before these - functions. - - savetty() and resetty() save and restore the state of the - terminal modes. savetty() saves the current state in a buffer, - and resetty() restores the state to what it was at the last call - to savetty(). - - curs_set() alters the appearance of the cursor. A visibility of - 0 makes it disappear; 1 makes it appear "normal" (usually an - underline) and 2 makes it "highly visible" (usually a block). - - ripoffline() reduces the size of stdscr by one line. If the - "line" parameter is positive, the line is removed from the top - of the screen; if negative, from the bottom. Up to 5 lines can - be ripped off stdscr by calling ripoffline() repeatedly. The - function argument, init, is called from within initscr() or - newterm(), so ripoffline() must be called before either of these - functions. The init function receives a pointer to a one-line - WINDOW, and the width of the window. Calling ripoffline() with a - NULL init function pointer is an error. - - napms() suspends the program for the specified number of - milliseconds. draino() is an archaic equivalent. - - resetterm(), fixterm() and saveterm() are archaic equivalents - for reset_shell_mode(), reset_prog_mode() and def_prog_mode(), - respectively. - - Return Value: - All functions return OK on success and ERR on error, except - curs_set(), which returns the previous visibility. - - Portability X/Open BSD SYS V - def_prog_mode Y Y Y - def_shell_mode Y Y Y - reset_prog_mode Y Y Y - reset_shell_mode Y Y Y - resetty Y Y Y - savetty Y Y Y - ripoffline Y - 3.0 - curs_set Y - 3.0 - napms Y Y Y - draino - - resetterm - - fixterm - - saveterm - - -**man-end****************************************************************/ - -#include <string.h> - -RIPPEDOFFLINE linesripped[5]; -char linesrippedoff = 0; - -static struct cttyset -{ - bool been_set; - SCREEN saved; -} ctty[3]; - -enum { PDC_SH_TTY, PDC_PR_TTY, PDC_SAVE_TTY }; - -static void _save_mode(int i) -{ - ctty[i].been_set = TRUE; - - memcpy(&(ctty[i].saved), SP, sizeof(SCREEN)); - - PDC_save_screen_mode(i); -} - -static int _restore_mode(int i) -{ - if (ctty[i].been_set == TRUE) - { - memcpy(SP, &(ctty[i].saved), sizeof(SCREEN)); - - if (ctty[i].saved.raw_out) - raw(); - - PDC_restore_screen_mode(i); - - if ((LINES != ctty[i].saved.lines) || - (COLS != ctty[i].saved.cols)) - resize_term(ctty[i].saved.lines, ctty[i].saved.cols); - - PDC_curs_set(ctty[i].saved.visibility); - - PDC_gotoyx(ctty[i].saved.cursrow, ctty[i].saved.curscol); - } - - return ctty[i].been_set ?
