Detailed Description

Macro Definition Documentation

MPSC_PBUF_FULL

#define MPSC_PBUF_FULL   BIT(3)

#include <zephyr/sys/mpsc_pbuf.h>

Flag indicated that buffer is currently full.

MPSC_PBUF_MAX_UTILIZATION

#define MPSC_PBUF_MAX_UTILIZATION   BIT(2)

#include <zephyr/sys/mpsc_pbuf.h>

Flag indicating that maximum buffer usage is tracked.

MPSC_PBUF_MODE_OVERWRITE

#define MPSC_PBUF_MODE_OVERWRITE   BIT(1)

#include <zephyr/sys/mpsc_pbuf.h>

Flag indicating buffer full policy.

If flag is set then when allocating from a full buffer oldest packets are dropped. When flag is not set then allocation returns null.

MPSC_PBUF_SIZE_POW2

#define MPSC_PBUF_SIZE_POW2   BIT(0)

#include <zephyr/sys/mpsc_pbuf.h>

Flag indicating that buffer size is power of 2.

When buffer size is power of 2 then optimizations are applied.
