wrapper ip format

[kyy13]

Create IPv4 and IPv6 formats that can be converted to/from string rather than supply a string to socket sender/receiver.

[kyy13]

Note that format needs to he exposed to main API as well

[kyy13]

struct IPv4Address
{
    uint8_t octets[4];
};

struct IPv6Address
{
    uint16_t segments[8];
};

[kyy13]

enum IpVersion : uint8_t
{
    IP_V4,
    IP_V6,
};

// IP represented in bytes
// IPv4 readable format by byte number is
//   [0].[1].[2].[3]
// IPv6 readable format by byte number is
//   [0][1]:[2][3]:[4][5]:[6][7]:[8][9]:[10][11]:[12][13]:[14][15]
//   NOTE: Byte pairs (e.g. [0][1]) in Big Endian byte order
union IpAddress
{
    uint8_t ip_v4[4];
    uint8_t ip_v6[16];
};

[kyy13]

void udcConvertStringToIp(const char* str, IpVersion* version, IpAddress* address);

void udcConvertIpToString(IpVersion version, IpAddress address, char* str);

[kyy13]

needs to be typedef uint8_t[16] IpAddress;
because no unions in C

[kyy13]

enum UdcAddressFamily
{
    UDC_IPV4,
    UDC_IPV6,
};

struct UdcAddress
{
    uint8_t bytes[16];
};

struct UdcAddressIPv4
{
    uint8_t bytes[4];
};

struct UdcAddressIPv6
{
    uint8_t bytes[16];
};

UdcAddressIPv4 udcConvertToIPv4(UdcAddress);

UdcAddressIPv6 udcConvertToIPv6(UdcAddress);
