Field Documentation

◆ flags

u8_t pbuf::flags

misc flags

Definition at line 102 of file pbuf.h.

◆ len

u16_t pbuf::len

length of this buffer

Definition at line 96 of file pbuf.h.

◆ next

struct pbuf* pbuf::next

next pbuf in singly linked pbuf chain

Definition at line 81 of file pbuf.h.

◆ payload

void* pbuf::payload

pointer to the actual data in the buffer

Definition at line 84 of file pbuf.h.

◆ 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 109 of file pbuf.h.

◆ 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)

Definition at line 93 of file pbuf.h.

◆ type

u8_t pbuf::type

pbuf_type as u8_t instead of enum to save space

Definition at line 99 of file pbuf.h.
