BUFFER_SIZE

Size in bytes of the shared buffer

This holds the size of the circular buffer shared between producer and consumer

Function Documentation

void* consumer_thread

(

void *

arg

)

Consumerer routine.

This is the routine for the consumer. It consumes one byte at a time from the shared buffer.

int main	(	int	argc,
		char **	args
	)

Main routine.

The main will have to:

1. Parse the parameters
2. Initialize the semaphore
3. Initialize the shared buffer
4. Span producers and consumers

Parameters

argc	number of parameters
args	command line parameters

Returns

0 on sucess, 1 on error
