int ok = SendIPCMessage(STRPTR port, UBYTE *data, int len, struct hwTagList *tags);
datato the IPC port specified by
port. The length of the message specified by
datais specified in the
lenparameter (in bytes). Note that
datacould also contain binary data. If the port name specified in
portdoesn't exist or an error occurs,
Note that since
SendIPCMessage() may be used to send messages to different
processes, the receiver's port must be specified as a string instead of a handle
created by CreateIPCPort() because handles are of course
private to the process that created them.
When an IPC port receives a message, it should post it to Hollywood's event queue
HWEVT_USERMESSAGE event type. See hw_PostEvent for details.
