Hi!
I’m using LWIP 2.0.3. In my code I have a static NTP server address.
But this address can be invalid or valid (depending what the user will
write in it). If DHCP is enabled I want to reach the following behavior:
* If the NTP server address is delivered via the DHCP, it will be set
and used (it doesn’t matter what is the static address).
* If the NTP server address is not delivered via the DHCP and the
static NTP server address is invalid, the NTP will not be initialized.
* If the NTP server address is not delivered, but the static NTP
server address is valid, the NTP will be initialized and will use
the static address.
To reach this, I need to decide what to do in the call of the function
dhcp_set_ntp_address(). But there is no callback, so I cannot call my
own code. How can I reach this behavior without modifying the original
code of the stack (file sntp.c)?
