So i want to ask you: is there some syscall or methods to build a raw socket,?

Cocoa is a high-level frameworks and doesn't have direct support for this low-level stuff (direct device access, raw sockets, etc). However, Mac OS X supports a standard BSD sockets API (Mac OS X network is, after all, based on BSD), so code written to sockets should work just fine, including inside a Cocoa application. Two points to note:

1. Different platforms have subtle differences in how they implement the 'sockets' API, especially when it comes to low-level stuff like raw sockets and ARP. You may encounter some of these differences when porting your code to a BSD-based platform, like Mac OS X. If so, try searching the net for hints. For example:

2. Cocoa does have support for integrating a socket, any type of socket, into the Cocoa runloop using CFSocket. Also, there are a variety of non-Apple Cocoa networking frameworks available. See the URL below for a good summary.
