Here is some little questions :
Is there an equivalent of getkey() who doesn't wait (taking keys pressed
'on the fly' like kbhit() ) ?

How to use correctly time() ? I tried to make a countdown of 3 sec :

float quantum=3;
time_t t=time(NULL);
while (time(NULL) - t < quantum) {
  // display the decount to the screen by example
}
 
it works, in fact it works till quantum=1, below (like quantum=0.1) it acts
as quantum=1, why ?
maybe the second is the unit of the function time() ?

and my last question : How to retrieve the char displayed at a certain
position of the screen ? Is there a possibility to do that with PDcurses ?

thx for reading !
