Divert Socket And Q. About Raw Socket

[soheil soheil]

Dear List
first :
I want to know if there is any sample of divert socket usage and divert socket programming?
I see the ipfw manual it says divert socket is used but when i goto /usr/src/sbin/ipfw
and trace ipfw.c
i cannot find anything about divert socket i just found a raw socket.

second:
When i use this code of C (main.c)
....//include sections
int main()
{
int s,fd;
char buff[4096];
printf("going to make SD ");
s = socket(PF_INET, IP
printf("going to read");
soheil: read(s, buff, 4096); // or recv(s,buff,4096, 0);
printf("done");
return 0;
}


After i compile it nothing about output on the screen ( none of printfs are executed ) when i comment out the line labled by soheil it works and output :going to make SD going to read ....

I don't know why please help me.
THANX alot
Soheil hassas yeganeh
