Hi ,
    How can i read a memory location in the PC at 0000:046Ch which contains
a 32-bit value of the number of ticks from 1970 using djgpp ?

    And why the following piece of code does not work ?


long Timer_Query(void)
{
  // this function is used to record the current time
long *clock(long *)0x0000046CL;
return(*clock);
}
  

in main event loop :

  while(!done)
{
 
 /* obtain starting time */
  start_time = Timer_Query();
  
  /* do some stuff here */
 

 /* now determine if a clock tick has passed */
  while((Timer_Query) - start_time)<WAIT_TIME);
   

}


Thanks for the help,

Luiz Fernando
