Producer – consumer process, Operating System

Assignment Help:

Step by step displays the content, and the final result of the list ("buffer") of 6 elements as the initial values ??and the following elements which are produced (NEXTP) or consumed (NEXTC). This scheme allows a maximum of (Buffer_size - 1) elements.

#define BUFFER_SIZE 6

typedefstruct { ....}item;

item buffer[BUFFER_SIZE];

int in = 0;

int out = 0;

Producer

itemnextProduced;

while (true)

{.../* produce an item in nextp */

while (((in + 1) % BUFFER_SIZE ) = = out)

/* loop, do nothing */;

buffer[in] = nextp;

in = (in + 1) % BUFFER_SIZE;

}

Consumer

itemnextConsumed

while (true)

{...

while ( in = = out) ; /* loop, do nothing */;

nextc = buffer [out];

out = (out + 1) % BUFFER_SIZE;

/* consume the item in nextc */

}
