 NAME
MP_DeregisterForObjectVisibilityChanges - deregister a client function

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

MP_STATUS MP_DeregisterForObjectVisibilityChanges(
 MP_OBJECT_VISIBILITY_FN pClientFn, MP_OBJECT_TYPE objectType,
 MP_OID pluginOid);




 PARAMETERS
pClientFn


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



objectType


The type of object the client wishes to deregister for visibility 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_DeregisterForObjectVisibilityChanges() function deregisters a
client function to be called whenever a high level object appears or
disappears.


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


The function specified by pClientFn will no longer be called whenever
high level objects appear or disappear.

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



MP_STATUS_SUCCESS


The pClientFn parameter is deregistered successfully.



MP_STATUS_FAILED


The pClientFn parameter deregistration is not possible at this time.
