I tried to see in lwiplib.c file, if there is a function like

I don't know that file, which suggests it is not part of lwIP itself
but rather part of a specific lwIP port.
You are right. It's part of the Stellaris-Port that TI did. According
to the documentation, the function he mentioned uses either
netif_set_addr or does the DHCP stuff needed to get/change the
IP-Adress:
//! This function will evaluate the new configuration data. If necessary, the

//! with the new configuration.
I have got a connection running in listening mode on a particular
port. For giving Dynamic DNS provision, i need to change the port
number of my listening connection at run time.
I don't understand this one. What exactly do you want to achieve? I
don't yet get why you need to change the port number of your LISTENING
port at runtime?
