MP_DeregisterForObjectPropertyChanges(3MPAPI) Common Multipath Management Library Functions MP_DeregisterForObjectPropertyChanges(3MPAPI)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 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.

MP_RegisterForObjectPropertyChanges - register a client function to be called
SYNOPSIS
cc [ flag... ] file... -lMPAPI [ library... ]
#include <mpapi.h>
MP_STATUS MP_RegisterForObjectPropertyChanges(
MP_OBJECT_PROPERTY_FN pClientFn, MP_OBJECT_TYPE objectType,
void *pCallerData, MP_OID pluginOid);
PARAMETERS
pClientFn A pointer to an object ID that has type MP_OBJECT_PROPERTY_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.
objectType The type of object the client wishes to register for property change callbacks.
pCallerData 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.
pluginOid 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.
DESCRIPTION
The MP_RegisterForObjectPropertyChanges() function registers a client function to be called whenever the property of an object changes.
The function specified by pClientFn is called whenever the property of an object changes. For the purposes of this function, a
property is defined to be a field in an object's property structure and the object's status. Therefore, the client function is not called
if a statistic of the associated object changes. But, it is called when the status changes (e.g., from working to failed) or when a name or
other field in a property structure changes.
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.
If multiple properties of an object change simultaneously, a client function can be called only once to be notified that all the changes
have occurred.
RETURN VALUES
MP_STATUS_INVALID_OBJECT_TYPE
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.
MP_STATUS_OBJECT_NOT_FOUND
The pluginOid owner ID or object sequence number is invalid.
MP_STATUS_INVALID_PARAMETER
The pCallerData is null or if the pluginOid has a type subfield other than MP_OBJECT_TYPE_PLUGIN, or when objectType is invalid.
MP_STATUS_SUCCESS
The operation is successful.
MP_STATUS_FN_REPLACED
An existing client function is replaced with the one specified in pClientFn.
