Look at the example programm from allegro (ex14.c) it demonstrate how to
use the GUI-Routines from Allegro to do that, or programm an input routine
yourself like this:

/**************** begin ****************/
#include <allegro.h>

void getline(char *buf, int x, int y, int color)
{
 char c;
 int i;

 for(i = 0;  (c = readkey() & 0xff) != '\n' && c != '\r'; ++i) {
    buf[i] = c;
    buf[i+1] = '_';
    buf[i+2] = '\0';

    textout(screen, font, buf, x, y, color);
 }
 buf[i] = '\0';
}

int main()
{
 char buf[100];

 allegro_init();
 install_keyboard();
 install_timer();

 set_gfx_mode(GFX_VGA, 320, 200, 0, 0);

 getline(buf, 100, 20, 15);

 allegro_exit();
}
/**************** end ****************/

It works, but it may need some improvements.
