Follow-up Comment #20, bug #19347 (project lwip):
Yes, "global" semaphore is a good idea, but in this case, we can't propose a
nice "integrated" netifapi for callers :
//draft
err_t
netifapi_dhcp_stop( netif* mynetif)
struct netifapi_msg msg;
msg.type = NETIFAPI_MSG_DHCP_STOP;
msg.netif = my_netif;
msg.sem = netifapi_sem;
if (tcpip_netifapi(&msg)!=ERR_OK) {
/* error handler */
}
}
Here, netifapi_sem is not defined. It can be done inside netifapi_dhcp_stop
(and I think we can, because the part of the api don't have to got a high
performance: we don't start/stop shcp or add/remove netif each n
milliseconds, isn't it? So, a integrate semaphore is a "nice" solution.
Another one is to define global semaphores and to add a netifapi_init() to
initialize them. But It can cause others multithread problem (two interfaces
add in the same time by example).
Your opinion about that?
>since the code has to run inside the context of a thread in tcpip.c
Yes, but it's the same for api_msg, but in a extra file.
