INT NET_SendVar ( <WORD connection> , <BYTE POINTER data> , <INT length> , [<BYTE includeseparator>] )
Sends data in array form or a byte, word or int or whatever other variable.
A null character on the end is not needed:
NET_SendVar( netid , &data , sizeof(data_element)*elements );
Or send an integer:
NET_SendVar( netid , &my_int , sizeof(int) );
Or send a struct:
NET_SendVar( netid , mystruct , sizeof(mystruct) );
Parameters
| WORD connection | - The connection identifier. |
| BYTE POINTER data | - The pointer to the data/variable. |
| INT length | - The length/size of the data/variable. |
| [BYTE includeseparator] | - true/false: whether the connection's separator will be added to the data 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 data is too big. |
| 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.
