[lwip-devel] [patch #5960] Enable multithread send/recv operations on same socket on TCP netconns

[Simon Goldschmidt]

Follow-up Comment #18, patch #5960 (project lwip):

>It could be good, but there is ONE case where it's necessary to let it at
inside "netconn" struct: the connect !!!

I think you got me wrong. I meant to include a sys_sem_t field in struct
api_msg_msg so that all the do_* functions don't post to conn->sem (like
conn->mbox until now) but post to msg->sem instead (same for pend in
tcpip_apimsg()). That way, you are free to set this sem to conn->sem or to
use a per-thread sem and api_lib.c is the only file where to chose (tcpip.c
and api_msg.c would always use this msg.sem).
