 MP_DEREGISTERFOROBJECTPROPERTYCHANGES 3MPAPI "June 13, 2021"
 NAME
MP_DeregisterForObjectPropertyChanges - deregister a previously registered
client function

 SYNOPSIS
cc [ flag.\|.\|. ] file.\|.\|. -lMPAPI [ library.\|.\|. ]
#include <mpapi.h>

MP_STATUS MP_DeregisterForObjectPropertyChanges(
 MP_OBJECT_PROPERTY_FN pClientFn, MP_OBJECT_TYPE objectType,
 MP_OID pluginOid);




 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


The type of object the client wants to deregister for property change
callbacks.



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.

 RETURN VALUES
MP_STATUS_INVALID_OBJECT_TYPE


The pluginOid parameter does not specify any valid object type. This is
most likely to happen if an uninitialized object ID is passed to the API.



MP_STATUS_INVALID_PARAMETER


The pluginOid parameter is not zero and has a type subfield other than
MP_OBJECT_TYPE_PLUGIN.



MP_STATUS_OBJECT_NOT_FOUND


The pluginOid owner ID or object sequence number is invalid.



MP_STATUS_UNKNOWN_FN


The pClientFn parameter is not the same as the previously registered
function.



MP_STATUS_SUCCESS


The pClientFn parameter is deregistered successfully.



MP_STATUS_FAILED


The pClientFn parameter deregistration is not possible.
