# :zap: Spark :zap: #
Small and easy to use network library that support raw socket, pcap file and contains API to easily manipulate the main Internet protocols.
# How to use #
## Building library ##
Check out the latest version with:
$ git clone https://github.com/jacopodl/spark
or download .zip from [release]() page.
Now you can build library in this way: \
(Spark required cmake to automate build process, please install cmake first!)
$ cd spark
$ cmake .
$ make
If the build finishes without errors :tada:, the compiled library will be located in the bin directory and related header files will be located in include directory.
## Quick tour ##
### Packet sniffer ###
```C
unsigned char buf[4096];
struct SpkSock *rsock;
struct SpkPcap *mypcap;
struct SpkTimeStamp ts;
int err;
int len;
int max_packet = 1000;
if((err = spark_opensock("my-interface", sizeof(buf), &rsock)) < 0)
{
fprintf(stderr, "%s\n", spark_strerror(err));
return -1;
}
if((err = spark_pnew("my-pcap", SPKPCAP_SNAPLEN_DEFAULT, spark_getltype(rsock), &mypcap)) < 0)
{
fprintf(stderr, "%s\n", spark_strerror(err));
return -1;
}
while(max_packet-- > 0)
{
len = spark_read(rsock, buf, &ts);
spark_pwrite(mypcap, buf, len, &ts);
}
spark_close(rsock);
spark_pclose(mypcap);
```
### Polymorphic types ###
```C
void addr_printer(struct netaddr *addr)
{
if(NETADDR_CMP_TYPE((*addr), NA_TYPE_MAC))
printf("This is MAC address!\n");
else if(NETADDR_CMP_TYPE((*addr), NA_TYPE_IP))
printf("This is IPv4 address!\n");
else if (NETADDR_CMP_TYPE((*addr), NA_TYPE_IP6))
printf("This is IPv6 address!\n");
else
printf("Generic/unknown address!\n");
}
int main()
{
netaddr_mac(macaddr);
netaddr_ip(ipaddr);
addr_printer(&macaddr);
addr_printer(&ipaddr);
}
```
