[lwip-users] tcp_write with zero-copy

[Reither Robert]

Hi lwip users,

i'm using the raw-interface with lwip 1.1.0 and want to avoid the buffer-copy 
at tcp_write.
Is there a regular path to deliver the data by giving a PBUF_TRANSPORT instead 
of a raw data buffer to
tcp_write (or another tcp_output function) just like in sending udp-data,
or do i have to patch the sources to do this ?
(e.h. use a special value of the copy-flag to just assume the buffer being a 
pbuf)

Greetings

Robert
