I am trying to write a simple program that will turn on a designated pin of
the parallel port, at a designated time.  I have found the following code,
but I can't get it to compile under DJGPP:

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

void main(void)   
{                 
struct time t;
unsigned port = 0x378;
while()
    {
    gettime(&t);
    if(t.ti_hour==10 && t.ti_min==05) _outp8(port,1);
    else _outp8(port,0);
    }
}

It is supposed to turn on pin 2 at 10:05 everyday for one minute.  Can
anyone please help me?  I am a VERY inexperienced programmer, and the books
I have don't seem to cover par ports.  Thanks.
