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)?

 

Best regards!
