Re: [lwip-users] how to send fragmented data via TCP?

UDP is "message based", you provide the whole payload and it will be sent in a datagram. TCP is "stream" based, data will be sent as it thinks it is best. As long as you don't set TCP_WRITE_FLAG_COPY in apiflags, tcp_write() will handle your data by building a PBUF_REF for each call and chaining

Shouldn't be a problem. Just call tcp_write with the buffer pointer and size and LWIP will take care of the rest. On Wed, Dec 16, 2015 at 10:00 PM, Yuxin Ren wrote: > Hi, > > I am using lwip raw API. > I want to send TCP packet without copy. > In my case, my application

[lwip-users] how to send fragmented data via TCP?

Hi, I am using lwip raw API. I want to send TCP packet without copy. In my case, my application generates the TCP payload, but the payload is fragmented. For example, it generates http header and http data, but the header and data are not continuous in memory. Can I send such payload as a pbuf
