Question

I want the user to enter a MAC address in the format : aa:bb:cc:dd:ee:ff and then I take this in my code as argv[1] for example.

Now how do I store this in an array in hex format?

What I need is the array to look like this:

char temp[6] = { 0xaa,0xbb,0xcc,0xdd,0xee,0xff }

Any ideas?

Answer 1

int a, b, c, d, e, f; 

sscanf(argv[1], "%x:%x:%x:%x", &a, &b, &c, &d, &e, &f);

Use ints to get the values, then you can place them in char array, since they have byte values.
