hi,
   in ecos tcp/ip stack, in support.c,these three functions was like this:

void 
microtime(struct timeval *tp)
{
    panic("microtime");
}

void
get_mono_time(void)
{
    panic("get_mono_time");
}

void 
csignal(pid_t pgid, int signum, uid_t uid, uid_t euid)
{
    panic("csignal");
}

I want know whether they was be called at real condition?

This is the older TCP/IP stack in net/tcpip only that is like this. The
bsd_tcpip stack is okay.

From what I can see, only one of those functions could be called in real
conditions. microtime() could be called if an ICMP timestamp is requested;
get_mono_time() is only used by the ipv6 code in the old net stack, and so
is irrelevant since IPv6 is not supported for it anyway; and csignal will
never be called.

If you want to submit a patch against the old net/tcpip stack to fix
microtime() you could, although that isn't a high priority for us so it
probably won't happen unless you do it.
