Thread: Question about Bounded Buffer

Hello

Shared Memory Solution

# difine BUFFER_SIZE 10 
typedef struct{
.....
} item;
 
item buffer[BUFFER_SIZE];
int in=0;
int out=0;

this code for producer

while (true) {
/* produce an item */ 
while (((in=(in+1)%BUFFER SIZE count)==out);
/* do nothing --  no free buffers */
buffer[in]= item;
in=(in+1)%BUFFER SIZE ;
}

this code for consumer

while (true){
while (in==out)
//do nothing -- nothing to consume 
 
//remove an item from the buffer 
item = buffer[out];
out =(out+1)% BUFFER SIZE ;
return item ;
 
}

this solution is correct , but can only use BUFFER_SIZE-1elements
