$8//$ Define buffer and condition variables

$```$

Then include declarations for the mutex, condition variables, and other variables.

$```$

$8//$ Define buffer and condition variables

$9$#define BUFFER$\_$SIZE $10$

$10$

$1$ int buffer$[$BUFFER$\_$SIZE$]$;

int count $=0$; $//$ How many things are in the buffer

$3$ pthread$\_$mutex$\_$t mutex; $//$ A mutex lock

$4$pthread$\_$cond$\_$t not$\_$full; $//$ A condition variable for a not$-$full buffer

p pthread$\_$cond$\_$t not$\_$empty; $//$ A condition variable for a not$-$empty buffer

$16$

$17//$ Define the number of items to produce$/$consume

$18//$ and the number of producer$-$consumer pairs

$19$ int NUM$\_$THREAD$\_$PAIRS $=1$;

$20$ int NUM$\_$ITEMS $=10$;

$21$

$22//$ Define the time it takes to produce and consume items

$23$ int PRODUCE$\_$TIME $=1$;

$24$ int CONSUME$\_$TIME $=2$;

$```$

For simplicity, this program is set up so there are the same number of producers as consumers.

Currently, it takes twice as long to consume an item as it does to produce an item. We'll be changing this later.
