[lwip-devel] [patch #5919] Create compile switch to remove select code

[Frédéric Bernon]

Follow-up Comment #11, patch #5919 (project lwip):

I think to extend LWIP_SO_RCVTIMEO to TCP connections. It will be the same
code, or something near...

But, I don't like this part of code in netconn_recv:

    /* If we are closed, we indicate that we no longer wish to receive
       data by setting conn->recvmbox to SYS_MBOX_NULL. */
    if (p == NULL) {
      memp_free(MEMP_NETBUF, buf);
      sys_mbox_free(conn->recvmbox);
      conn->recvmbox = SYS_MBOX_NULL;
      return NULL;
    }

I think it's not very thread-safe...
