Why isn't there an API for network configuration and related stuff ? Any OS should provide these interfaces for developers to write code that they want. Asking developers to use some system utility is restricting them to do what the utility offers.
What if i want to enhance the functionality of ifconfig? how do i do that? or what if i want to write something that is better then ifconfig?
