Hello and help!

[Stig]

Firstly hello all!

I am writing an audit tool for a pet project to pass away the boredom at work (and so in future I just run the program and save hours of work)

What I am trying to do is read in an IP address and then based on the subnet mask do calculations on the correct octect

e.g. 192.168.2.60 with a 23 bit mask I would start my calculations on the 3rd octect (2).

What I want to do is this. Let the user input the address and then read each octect into seperate integer values so that

int1=192
int2=168

etc.

The intial variable is a string but how do I scan for each of the elements. I would suspect the best way would be to search for the first to scan until the . then after the . for the next 3. Can anyone show me how to do this please?

The code I have works but only if the user inputs the last octect (thus limiting me to calculations on 24 to 32 bit masks)

Any help greatly appreciated. By the way I am using a gcc compiler so I can port over to any gcc platform.

Can you say 'delimiter'?

Yes. Or a simple switching routine could do the trick. Hint: Encountering a '.' is your cue to copy...

Hmm... maybe this example program will help...

#include <stdio.h>

int main ()
{
 int i;
 int o1, o2, o3, o4;
 i = scanf ("%d.%d.%d.%d", &o1, &o2, &o3, &o4);
 printf ("You entered %d octets.\n", i);
 return 0;
}

I'm not sure of exactly what you want, but this seems like it might have the answer.

thanks guys

Question, I tried something similar a while back but the gcc didnt like it, I prob missed something so will try yours. Will keep you posted on progress

[Stig]

GRRRRRRRrrrrrrrrrrrrrrrrr guess who looked back at old code, found the obvious mistake!

Cheers Q, that worked a bloody treat!
