btw, it seems that winsock provides raw icmp sockets ... why not use them ?

Im quite new to C, i've got several years of expirience with Java, but java does not support icmp sockets. All i need is a console program that can do pings to arbitrary addresses and with variable TTL (so i can do a trace route). Can i use winsock for this and can i use it in my comercial program without restrictions? Where can i get the winsock libraries?

Are there any free libraries for writing my own ICMP packets and sockets in C for Windows, and can i compile them with gcc?<br />
I need to use my own trace route in a application of mine so it must not be any restrictive licenses since my program is shareware.<br />
<br />

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.
