[lwip-devel] Question about unsent_oversize reset by zero length pcb in tcp_write()

[Axel Lin]

Hi,
tcp_write() allows a pcb with len=0.  (tcp_write_checks() return
ERR_OK if len is 0)
In this case, nothing add to pcb->unsent list and last_unsent->len is
not changed
but pcb->unsent_oversize will be set to 0.
I'm wondering if this is correct or not. Comments?

Regards,
Axel
