Functions
void	mpsc_pbuf_init (struct mpsc_pbuf_buffer buffer, const struct mpsc_pbuf_buffer_config config)
	Initialize a packet buffer. More...

union mpsc_pbuf_generic *	mpsc_pbuf_alloc (struct mpsc_pbuf_buffer *buffer, size_t wlen, k_timeout_t timeout)
	Allocate a packet. More...

void	mpsc_pbuf_commit (struct mpsc_pbuf_buffer buffer, union mpsc_pbuf_generic packet)
	Commit a packet. More...

void	mpsc_pbuf_put_word (struct mpsc_pbuf_buffer *buffer, const union mpsc_pbuf_generic word)

	Get current memory utilization. More...

int	mpsc_pbuf_get_max_utilization (struct mpsc_pbuf_buffer buffer, uint32_t max)
	Get maximum memory utilization. More...
