Stopping the cursor from moving

Is there anyway that I can stop the cursor from moving from a set point on my screen?

Say I have this (very simple) code:

Code:

---


printf("Enter a number (0-9) ->");
scanf("%d", &number);

---

The cursor would start off after the arrow, but could be moved around before the number was entered (Say by pressing enter and such), I was wondering if there was a way in which I can STOP the user from moving the cursor, for any reason other than to input?

And I'm aware I've been told about using scanf, but it's a simple example, and none to complex... bit like me :p

Thanks for any advice

Why don't you just scan for enter, and if it is pressed loop your input scanning? If you want to literally kill the cursor, I've only seen this for Windows:

Code:

---

#include <windows.h>

void KillCursor ( void );

void KillCursor ( void )
{
        CONSOLE_CURSOR_INFO cci;
        cci.dwSize = 1;
        cci.bVisible = FALSE;
        SetConsoleCursorInfo( GetStdHandle( STD_OUTPUT_HANDLE ), &cci );
}

To do what you ask requires non-standard functions, in order to read unbuffered keyboard input.

If you have Windows, and the getch() function in conio.h, you could try something like this:

Code:

---

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

int main(void)
{
        int c, i = 0;
        char buf[BUFSIZ];
       
        printf ("Your message >");
        while ((c = getch()) != EOF && c != '\n' && c != '\r')
        {
                if (isalnum(c))
                {
                        buf[i++] = c;  /* do some overflow checking!*/
                        putchar (c);
                }
        }
       
        buf[i] = '\0';
       
        printf ("\nbuf is >%s<\n", buf);
        return (0);
}

---

This is only sample code to show you how to get started, to use it properly requires further changes to make it safe. But it is safe to compile and run, just don't overfill that buffer!

Thanks for your help, I can see how I meant to do it now :D

Joy!
