Can anybody tell me what this script below do and how to convert it to Linux system? This script was used under MS-DOS. I am new to C programming so bear with me.


#include <time.h>
#include <graph.h>

wait(tsec) /* wait tsec seconds */
float tsec;
{
time_t start, finish;
double difftime(),delta,delta1;
struct videoconfig config;
struct rccoord rcoord1,rcoord2;
char buff[40];

if (tsec>10 ){
_getvideoconfig(&config);
rcoord1=_gettextposition();
}
time(&start); /* get start time */
time(&finish); /* get stop time */
while ((delta=difftime(finish,start))<tsec) { /* set up timer countdown */
if(tsec>10&&((delta-delta1)>=1)) {
sprintf(buff,"Timer ---[%g] \0",tsec-delta);
_settextposition(-100,60);
_outtext(buff);
delta1=delta;
}
time(&finish);

}
if (tsec>10)
_settextposition(rcoord1.row,rcoord1.col);
}

Shure, I am not gunna write the script for you, but just look into the "curses" library for that text output. The program looks really simple. Although I could understand it allot better if you would put it between [ code ] [ /code ] tags (with out the spaces).

Yes The_Nerd is right ncurses you need to use see http://www.gnu.org/software/ncurses/ncurses.html and

Uhm.. no you don't need ncurses (the typical replacement for the MSDOS conio lib).

In fact, unless you're going to be doing alot of fancy text-based graphical work in this program, I'd argue against it. ncurses is great when you need serious functionality. But when you don't, or only need cursor movement, and text colors, you don't need the bloat of curses.

Use ansi escape characters instead.

Here's a thread where they are discussed. I'd opt for this any day over curses -- why add that extra program overhead for a few simple functions?
