Field Documentation
◆ flags

◆ len
| u16_t pbuf::len |

◆ next
| struct pbuf* pbuf::next |
next pbuf in singly linked pbuf chain

◆ payload
| void* pbuf::payload |
pointer to the actual data in the buffer

◆ ref
| u16_t pbuf::ref |
the reference count always equals the number of pointers that refer to this pbuf. This can be pointers from an application, the stack itself, or pbuf->next pointers from a chain.
Definition at line 172 of file pbuf.h.
Referenced by pbuf_alloc(), pbuf_free(), and pbuf_ref().
◆ tot_len
| u16_t pbuf::tot_len |
total length of this buffer and all next buffers in chain belonging to the same packet.
For non-queue packet chains this is the invariant: p->tot_len == p->len + (p->next? p->next->tot_len: 0)

◆ type
| u8_t pbuf::type |
pbuf_type as u8_t instead of enum to save space
