Field Documentation

arg_t::buf

The shared buffer.

Producers will fill locations in this buffer, while consumers will read and print the bytes in the buffer.

arg_t::buf_size

holds the size of the shared ring buffer

This variable stores the size of the shared ring buffer

arg_t::open_sem

This semaphore holds the number of free locations.

This semaphore is used by the producer to produce a new byte in the shared buffer. It will be used by the consumer to notify that a byte has been consumed from the buffer.

arg_t::ready_sem

This semaphore holds the number of ready locations.

This semaphore is used by the producer to notify that a new byte in the shared buffer has been produced. It will be used by the consumer to understand that a byte can be consumed from the buffer.
