Instruction set reference
HIPE_OP_MESSAGE
Sends a user-defined message to another client, which must be a direct child of the sending client, or the direct parent of the sending client.
- location: Sending a message: A value of 0 (corresponding to the body element of the client frame) means the message should be sent to the direct parent of this client. A location corresponding to a child frame means send the message to the client connected to that frame. Receiving a message: A value of 0 (corresponding to body element) means the message came from the direct parent of this frame. A location value corresponding to a child frame means the message came from that client.
- arg[]: User defined message data may be passed through up to 4 arguments.
- requestor:: User defined message data may be passed through here.
Notes
Unlike most Hipe instructions, this instruction may be either sent or received by the client. It passes more or less straight through the server from one client to another.
