File Positioning stdout

Hi. Noob here just playing around with some things trying to learn. I was wondering if there is a way to print a stationary progress bar onto my console window. I tried ftell() and fseek() but that didn't work.

Code:

#include <stdio.h>

int main(void)
{
    long pos[11];
    int i, t;

    pos[0] = 0;
    printf("[");
    pos[1] = ftell(stdout);
    /* record current position */
    for (i = 2; i < 10; ++i)
    {
        putchar('-');
        pos[i] = ftell(stdout);
    }

    printf("-]");
    /* print progress bar */
    for (i = 1, t = 10; t > 0; ++i, --t)
    {
        fseek(stdout, pos[i], SEEK_SET);
        putchar('=');
    }

    return 0;
}

Output:

[T3256@GURY GibletSearch]$ ./temp

I'm trying to overwrite the dashes. [==========].

Thanks.

You can use backspace in a string ('\b'). Ie, backspace, then replace the remaining '-' that you backspaced over.

Anything more complicated than that and you will need a text console library such as ncurses (any OS) or winAPI.

Thank you kind sir.
