cc [ flag.\|.\|. ] file.\|.\|. -lMPAPI [ library.\|.\|. ] #include <mpapi.h> MP_STATUS MP_RegisterForObjectVisibilityChanges( MP_OBJECT_PROPERTY_FN pClientFn, MP_OBJECT_TYPE objectType, void *pCallerData, MP_OID pluginOid);
A pointer to an object ID that has type MP_OBJECT_VISIBILITY_FN function defined by the client. With a successful return, this function is called to inform the client of objects that have had one or more properties changed.
The type of object the client wishes to register for property change callbacks.
A pointer that is passed to the callback routine with each event. This might be used by the caller to correlate the event to the source of the registration.
If this is a valid plugin object ID, then registration is limited to that plugin. If this is zero, then the registration is for all plugins.
The MP_RegisterForObjectVisibilityChanges() function registers a client function to be called whenever the property of an object changes. The function specified by pClientFn is called whenever objects appear or disappear.
It is not an error to re-register a client function. However, a client function has only one registration. The first call to deregister a client function will deregister it no matter how many calls to register the function have been made.
The pluginOid or objectType does not specify any valid object type. This is most likely to happen if an uninitialized object ID is passed to the API.
The pluginOid owner ID or object sequence number is invalid.
The pCallerData is null or if the pluginOid has a type subfield other than MP_OBJECT_TYPE_PLUGIN, or when objectType is invalid.
The operation is successful.
An existing client function is replaced with the one specified in pClientFn.
