udp - Artnet Packet Structure -

even though have found many libraries allows programmers use artnet/artnetdmx protocol haven't found correct structure send out artnet in code (to socket).

the structure given but, can't figure out in order bytes should send. send byte universe 1 one, or need send byte array values?

doesn have experience in sending artnet on udp?

this structure given on wikipedia: http://i.stack.imgur.com/wujzd.png

i use following struct art-net v2

typedef struct {     char id[8];         //"art-net"     uint16 opcode;      // see doc. table 1 - opcodes eg. 0x5000 opoutput / opdmx     uint16 version;     // 0x0e00 (aka 14)     uint8  seq;         // monotonic counter     uint8  physical;    // 0x00     uint8  subuni;      // low universe (0-255)     uint8  net;         // high universe (not used)     uint16 length;      // data length (2 - 512)     uint8_t data[512];  // universe data } artnetdmx; 

if want write art-net application should read documentation located on artistic licence.

i follow version 2 (14) specification version 3 quite rare in wild.
