I have this little bit of code i need some one who knows something about the C language to tell me what it means.

Expand|Select|Wrap|Line Numbers
  1. ArtNetSendPacket("", (char *)&ArtDmxTx, length($T_ArtDmx));
I think it means that the command ArtNetSendPacket which is defined in a C header file, the IP address for that command but i dont under stand the next part (char *)... that it checks the length of T_ArtDmx

It takes the address of the value ArtDmxTX (that is it gets a pointer to it) and casts it to a pointer to a character.

I think the idea in this case, is to ignore the type of objects and treat it as raw bytes, so that it can be sent
