Example Program: TWO
This program shows how to handle two terminals from a single program.
#include <curses.h>
#include <signal.h>
struct screen *me, *you;
struct screen *set_term();
FILE *fd, *fdyou;
char linebuf[512];
main(argc,argv)
{
char **argv;
int done
0 ;
int c;
if (argc
!=
4) {
fprintf(stderr,"Usage: two othertty otherttytype inputfile\n");
exit(1) ;
}
fd
=
fopen(argv[3] ,"r");
fdyou
=
fopen(argv[1]
,"W+");
signal(SIGINT, done); /* die gracefully */
me
=
newterm(getenv(ITERM"),stdout,stdin); /* initialize my tty */
you
=
newterm(argv[2] ,fdyou,fdyou) ; /* Initialize his/her terminal*/
set_term(me);
noechoO;
cbreakO;
nonlO;
nodelay(stdscr,TRUE);
set_term(you) ;
noechoO;
cbreakO;
nonlO;
nodelay(stdscr,TRUE);
/* Set modes for my terminal */
/* turn off tty echo */
/* enter cbreak mode */
/* Allow linefeed */
/* No hang on input */
/* Dump first screen full on my terminal */
