Parameters

pClientFn

A pointer to an object ID that has type MP_OBJECT_PROPERTY_FN function defined by the client that was previously registered using the MP_RegisterForObjectPropertyChanges(3MPAPI) API. With a successful return this function will no longer be called to inform the client of object property changes.

objectType

pluginOid

If this is a valid plugin object ID, then registration will be removed from that plugin. If this is zero, then registration is removed for all plugins.

Description

The MP_DeregisterForObjectPropertyChanges() function deregisters a previously registered client function that is to be invoked whenever an object's property changes.

The function specified by pClientFn takes a single parameter of type MP_OBJECT_PROPERTY_FN.

The function specified by pClientFn will no longer be called whenever an object's property changes.
