Plugins that have the capability flag
HWPLUG_CAPS_IPCADAPTER set can replace Hollywood's
inbuilt handler for inter-process communication (IPC). Since inter-process communication
is often closely tied to display adapters, plugins that install their own display adapters
might also want to provide a custom adapter for inter-process communication. This plugin
type makes that possible.
Hollywood will call your CreateIPCPort() function to create a
port for inter-process communication. SendIPCMessage() will
be called whenever Hollywood wants to send a message to an IPC port. When an IPC port
receives a message, it must post it to Hollywood's event queue using the
event type. See hw_PostEvent for details.
Please note that IPC adapters are not automatically initialized when Hollywood loads
the plugin. Instead, you have to manually call hw_SetIPCAdapter()
in your RequirePlugin() function to activate the IPC adapter.
The IPC adapter will then only be activated if the user calls
@REQUIRE on your
plugin. Otherwise, Hollywood will use its default IPC handler. See Auto and manual plugin initialization for details.
See hw_SetIPCAdapter for information on how to install your IPC adapter.
This plugin type is supported since Hollywood 9.0.
