Although it could be fixed by making everything static, I felt that the 512 byte array plus about 80 bytes for initscr/endwin routines, (about 600 total) was just too much per file. So, I put the routines and array into a second file. This is no longer transparent; you will need to add bcurses.o to the makefile, or add bcurses.o to /usr/lib/libcurses.a Once again, this is a nearly transparent way to buffer curses output even in interactive programs. : use /bin/sh # shar cat > curses.h << \EOF_curses.h /* * %Z% %M% %I% %D% %Q% * * Copyright (C) Microsoft Corporation, 1983 * * This Module contains Proprietary Information of Microsoft * Corporation and AT&T, and should be treated as Confidential. */ /* @(#)curses.h 1.14 (Berkeley) 7/4/83 */ # ifndef WINDOW # include # include # define bool char # define reg register # define TRUE (1) # define FALSE (0) # define ERR (0) # define OK (1) # define _ENDLINE 001 # define _FULLWIN 002 # define _SCROLLWIN 004 # define _FLUSH 010 # define _STANDOUT 0200 # define _NOCHANGE -1 # define _puts(s) tputs(s, 0, _putchar); typedef struct sgttyb SGTTY; /* * Capabilities from termcap */ extern bool AM, BS, CA, DA, DB, EO, GT, HZ, IN, MI, MS, NC, OS, UL, XN; extern char *AL, *BC, *BT, *CD, *CE, *CL, *CM, *CR, *DC, *DL, *DM, *DO, *ED, *EI, *HO, *IC, *IM, *IP, *LL, *MA, *ND, *NL, *SE, *SF, *SO, *SR, *TA, *TE, *TI, *UC, *UE, *UP, *US, *VB, *VE, *VS, PC; /* * From the tty modes... */ extern bool NONL, UPPERCASE, normtty, _pfast; struct _win_st { short _cury, _curx; short _maxy, _maxx; short _begy, _begx; short _flags; bool _clear; bool _leave; bool _scroll; char **_y; short *_firstch; short *_lastch; struct _win_st *_nextp, *_orig; }; # define WINDOW struct _win_st extern bool My_term, _echoit, _rawmode, _endwin; extern char *Def_term, ttytype[]; extern int LINES, COLS, _tty_ch, _res_flg; extern SGTTY _tty; extern WINDOW *stdscr, *curscr; /* * Define VOID to stop lint from generating "null effect" * comments. */ # ifdef lint int __void__; # define VOID(x) (__void__ = (int) (x)) # else # define VOID(x) (x) # endif /* * psuedo functions for standard screen */ # define addch(ch) VOID(waddch(stdscr, ch)) # define getch() (fflush(stdout),wgetch(stdscr)) # define addstr(str) VOID(waddstr(stdscr, str)) # define getstr(str) (fflush(stdout),wgetstr(stdscr, str)) # define move(y, x) VOID(wmove(stdscr, y, x)) # define clear() VOID(wclear(stdscr)) # define erase() VOID(werase(stdscr)) # define clrtobot() VOID(wclrtobot(stdscr)) # define clrtoeol() VOID(wclrtoeol(stdscr)) # define insertln() VOID(winsertln(stdscr)) # define deleteln() VOID(wdeleteln(stdscr)) # define refresh() VOID(wrefresh(stdscr)) # define inch() VOID(winch(stdscr)) # define insch(c) VOID(winsch(stdscr,c)) # define delch() VOID(wdelch(stdscr)) # define standout() VOID(wstandout(stdscr)) # define standend() VOID(wstandend(stdscr)) /* * mv functions */ #define mvwaddch(win,y,x,ch) VOID(wmove(win,y,x)==ERR?ERR:waddch(win,ch)) #define mvwgetch(win,y,x) (wmove(win,y,x)==ERR?ERR:fflush(stdout),wgetch(win)) #define mvwaddstr(win,y,x,str) VOID(wmove(win,y,x)==ERR?ERR:waddstr(win,str)) #define mvwgetstr(win,y,x,str) (wmove(win,y,x)==ERR?ERR:fflush(stdout),wgetstr(win,str)) #define mvwinch(win,y,x) VOID(wmove(win,y,x) == ERR ?
