CodeScopeSTM32 Libraries and SamplesLwIPpbuf::tot_len

pbuf::tot_len field

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)

Syntax

u16_t tot_len;

Examples

pbuf::tot_len is referenced by 28 libraries and example projects.
