curses getch() help

[dincay]

Hi. I need a program that user enters characters but they shouldn't be visible on screen. So I wrote the following program. However getch() doesn't wait for a character to be entered and returns -1. The program exits immediately. I tried cbreak(), raw(), noecho() but they didn't work. I couldn't understand their meanings also. Where can be the problem?

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

int main(void)
{
int x,y;

printf("Enter two character\n");
x = getch();
y = getch();
printf("Entered Values = %c and %c\n",x,y);
printf("Entered Values = %d and %d\n",x,y);

return 1;
}

I have this old piece of code that might help. It grabs the text that's typed into a terminal and writes it to a file..

#include <iostream>
#include <fstream>
#include <termios.h>
#include <stdio.h>
#include <unistd.h>

int main(int argc, char**argv)
{
	std::ofstream			fout("datafile");
	if (fout.fail())
	{
		std::cout<<"could not open file!\n";
		unlink("test");
		return 1;
	}
	char ch;
	struct termios original_t, new_t;
	const int STDIN = 0;

	tcgetattr (STDIN, &original_t);
	new_t = original_t;
	new_t.c_lflag &= ~(ICANON|ECHO);

	std::cout<<"enter password->";
	tcsetattr (STDIN, TCSAFLUSH, &new_t);
	fflush(0);

	while ((ch = std::cin.get()) != '\n')
	{
		fout<<ch;
	}
	fout<<ch;
	fout.close();
	unlink("test");
	std::cout<<"\ngot password!\n";
	tcsetattr (STDIN, TCSANOW, &original_t);
	return 0;
}
