IPv6 parsing in C

Question

I wanted to know how I can parse an IPv6 address in C and convert it to a 128 bit value?

So a hex address like 1:22:333:aaaa:b:c:d:e needs to be convert

Answer 1

if you can use boost, something like this should work:

#include

using boost::asio::ip;

bool parseIpv6String(std::string ipv6_string, char* dest){
    try{
        address_v6 addr = address_v6::from_string(ipv6_string);
        memcpy(dest,addr.to_bytes().data(), 16);
    }catch(...){
        return false;
    }
    return true;
}

It is a bit more portable than for example POSIX specific functions.
