Member Data Documentation

flags

u16_t pbuf::flags

flags telling the type of pbuf, see PBUF_FLAG_

len

u16_t pbuf::len

length of this buffer

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.

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)
