I haven't seen before! getch() doesn't work!

Hello,

i compiled this programm under linux: $g++ -o test test.cpp -lncurses

#include <stdio.h>
#include <curses.h>

int main(void)
{
char c;

// while ((c = getchar()) != '\n'); //emtpy input buffer
c = getch();
printf("%c\n", c);
}

The output:

$ ./test
d
ÿ
$

Why does the programm recognize EVERY key as "ÿ"??

pls help
regards
StefanA.

Code:

---

int main(void)
{
char c;

// while ((c = getch()) != '\n') //emtpy input buffer
    {
    printf("%c\n", c);
    }

You had a ';' after your loop, dont you want to keep checking the letter and printing it if its not a '\n'? Try that.

getch() is included in the Conio.h Library.

it should be

Code:

---

#include <stdio.h>
#include <curses.h>
#include <conio.h>

---

NOTE use codetags

>>getch() is included in the Conio.h Library.
But (s)he said:
>>i compiled this programm under linux: $g++ -o test test.cpp -lncurses

getch() lives in ncurses libraries too.

You didn't init the screen, which I expect is your problem.

Try this:

Code:

---

#include <stdio.h>
#include <curses.h>

int main(void)
{
  int c;
 
  initscr();
  noecho();
  for ( ;; )
  {
    c = getch();
    printw("%c\n", c);
  }
  endwin();
 
  return 0;
}

Use CTRL+C to terminate it.

This is *nix talk, if you have any more questions, post them on the Linux forum and someone will help you.

Hello,

thanks for your help!

with other words, i have chosen the wrong function!
Is there any getch() like function, which isn't declared in conio.h or curses.h? I want the input not to be displayed on screen.

I ask, because i am programming under linux and cannot use conio.h and don't want to use the complex curses library...

Correct me if I am wrong, but isn't getch unique to DOS?

Correcting.... Getch() is in the conio.h header and isn't limited to
DOS (might it be in dos at all!).

You're wrong ;) Didn't you gather that from my previous post!?!

I guess so. However, the help file in Turbo C++ v3.0 said that getch (and getche) are unique to DOS. Howcome?
