Definition

INT NET_SendVar ( <WORD connection> , <BYTE POINTER message> , <INT length> , [<BYTE includeseparator>] )

Sends a message in array form or send a byte, word or int.

A null character on the end is not needed:

NET_SendVar( netid , &msg , sizeof(msg) );

Or send a struct:

NET_SendVar( netid , mystruct , sizeof(mystruct) );

Parameters

WORD connection	- The connection identifier.
BYTE pointer message	- The pointer to the message/variable.
INT length	- The length/size of the message/variable.
[BYTE includeseparator]	- true/false: whether the connection's separator will be added to the message at the end. Default is true.

Returns

INT : The size of the succesfully sent data. With the separatorlength, if the separator was added.

NET_ERROR_INVALIDCONN	- The connection is invalid.
NET_ERROR_CONNINACTIVE	- The connection is inactive.
NET_ERROR_MESSAGETOOLONG	- The message is too long.
NET_ERROR_SENDING	- Could not send.
>=0	- The size of the succesfully sent data. With the separatorlength, if the separator was added.

Notes

Make sure the data is received properly. If you send a struct, be sure the receiver knows he should be receiving a struct and then receive the struct like it should. NET_RecvVar() is helpful for this.
