ncurses

I'm currently attempting to write a minimal terminal multiplexer using ncurses. However, when I try to execv a shell, it doesn't print to the window, and instead starts a new subprocess that takes control of the window (i.e. ignores ncurses). How can I prevent that and have ncurses control it? Is there some way of getting the tty and controlling that? EDIT Thanks to Ross Ridge in the comments, I now know that I need to create a pseudo-terminal, which I then read into an ncurses window. However, I can't figure out how to get the stdout to print in an ncurses window. Is there an ncurses function

I successfully ran sudo apt-get install libncurses5-dev Within my Eclipse window I then try to build the following HelloWord.cpp program: #include <ncurses.h> int main() { initscr(); /* Start curses mode */ printw("Hello World !!!"); /* Print Hello World */ refresh(); /* Print it on to the real screen */ getch(); /* Wait for user input */ endwin(); /* End curses mode */ return 0; } I get the following error: Invoking: GCC C++ Linker g++ -m32 -lncurses -L/opt/lib -o "Test_V" ./src/curseTest.o ./src/trajectory.o ./src/xJus-epos.o -lEposCmd /usr/bin/ld: cannot find -lncurses collect2: error: ld

I'm writing a ncurses based chat program. At first, I wrote just networking stuff (without ncurses) and everything worked fine, but after adding graphics I can't get the client app to work properly. The main problem is reading from stdin and socket at the same time. In ncurses-less version I've used pthread and it worked like charm. Alas, it seems that pthread and ncurses don't go together very well, so I had to find another solution. I thought that select() would do, but it still only reads from stdin and completely ignores the socket. Here is the whole code: code The interesting part is:

I wrote this simple program on Windows. Since Windows has conio, it worked just fine. #include <stdio.h> #include <conio.h> int main() { char input; for(;;) { if(kbhit()) { input = getch(); printf("%c", input); } } } Now I want to port it to Linux, and curses/ncurses seems like the right way to do it. How would I accomplish the same using those libraries in place of conio? #include <stdio.h> #include <ncurses.h> int main(int argc, char *argv) { char input; initscr(); // entering ncurses mode raw(); // CTRL-C and others do not generate signals noecho(); // pressed symbols wont be printed to

while 1: ... window.addstr(0, 0, 'abcd') window.refresh() ... window size is full terminal size, big enough to hold abcd . If 'abcd' is modified to shorter string like 'xyz' , then on terminal I will see 'xyzd' . What exactly I am doing wrong? addstr() only prints the string you specify, it does not clear the following characters. You will have to do that yourself: To clear characters until the end of the line, use clrtoeol() , To clear characters until the end of the window, use clrtobot() . Let's suppose you have this code, and you just want to know how to implement draw() : def draw(window,
