HELP!!!
I am trying to use the curses package in a c program, and I can not determine
what my problem is. When I compile the program and run it, nothing happens
(i.e. no screen activity), but if I run it using dbx, the curses routines
work!. Any Ideas on what's wrong? (We do not have any curses manuals, only
a very weak man page. )
I am compiling with : cc -o test test.c -g -lcurses -ltermcap
our system is runing UTX 2.0 (4.3 BSD)
#include <stdio.h>
#include <curses.h>
main()
{
WINDOW *win;
initscr();
win=newwin(10,10,10,10);
box(win,'+','+');
wprintw(win,"this is a test");
wrefresh(win);
endwin();
exit(0);
};
Thanks for any help

I tried to run the program on one of our other systems, and everything ran fine! so it looks like it is something specifict to this individual machine. (if I had known that, I would have held off on the original post-Sorry!) -- +-----------------------+---------------------------------------------------+ | Duane L.

That could leave the cursor location at a spot outside of the window, in which case the print statement won't execute (at least in my version it quietly fails if asked to print outside of the legal boundaries. You should do one of the following: wmove(win, 0,0); wprintw(win, "this is a test"); or mvwprintw(win, 0, 0, "this is at test"); Either will work. -- --------------------- John Mundt Teachers' Aide, Inc.
