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_PROP‐
ERTY_FN function defined by the client that was previ‐
ously registered using the MP_RegisterForObjectProperty‐
Changes(3MPAPI) API. With a successful return this func‐
tion 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 pre‐
viously 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 parmeter 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 parmeter is not the same as the previously registered
function.
MP_STATUS_SUCCESS
The pClientFn parmeter is deregistered successfully.
MP_STATUS_FAILED
The pClientFn parmeter deregistration is not possible.
