Being really bored today I decided to port some winsock2 stuff from some VB stuff I found a few months ago. So here it is .
oh ya you need libws2_32.a as for the icmp stuff i don't know the .a for it so i have it rem out because i couldn't test it.
you can get the .a stuff from mingw32

oh ya you need libws2_32.a as for the icmp stuff i don't know the .a for it so i have it rem out because i couldn't test it.
you can get the .a stuff from mingw32
