This group contains the implementation to support the Object Handler in multiprocessing (MP) configurations.
This handler encapsulates functionality which is used to manage objects which have been declared to be globally visible. This handler knows objects from all of the nodes in the system.
◆ _Objects_MP_Allocate_and_open()
Allocates a global object control block and places it in the specified information table.
This routine allocates a global object control block and places it in the specified information table. If the allocation fails, then is_fatal_error determines the error processing actions taken.
- Parameters
-
[in,out] | information | Points to the object information table for this object class. |
| the_name | The name of the object being opened. |
| the_id | The Id of the object being opened. |
| is_fatal_error | Indicates whether not being able to allocate the object is considered a fatal error. |
- Return values
-
true | The operation succeeded. |
false | The allocation failed, but is_fatal_error was set to false. |
- Todo:
- This method only works for object types with 4 byte object names. It does not support variable length object names.
◆ _Objects_MP_Close()
Removes a global object from the specified information table.
This routine removes a global object from the specified information table and deallocates the global object control block.
- Parameters
-
[in,out] | information | Points to the object information table for this object class. |
| the_id | The id of the global object to remove. |
◆ _Objects_MP_Free_global_object()
void _Objects_MP_Free_global_object |
( |
Objects_MP_Control * |
the_object | ) |
|
This routine deallocates a Global Object control block.
- Parameters
-
[out] | the_object | The object to deallocate. |
◆ _Objects_MP_Global_name_search()
Looks for the object with the_name in the global object tables indicated by information.
This routine looks for the object with the_name in the global object tables indicated by information. It returns the ID of the object with that name if one is found.
- Parameters
-
| information | Points to the object information table for this object class. |
| the_name | The name of the object being searched for. |
| nodes_to_search | Indicates the set of nodes to search. |
[out] | the_id | will contain the Id of the object if found. |
- Return values
-
STATUS_SUCCESSFUL | The lookup was successful. |
STATUS_INVALID_NODE | The number of nodes is bigger than the objects maximum nodes value. |
STATUS_INVALID_NAME | There is no global object with this name. |
◆ _Objects_MP_Handler_early_initialization()
void _Objects_MP_Handler_early_initialization |
( |
void |
| ) |
|
Intializes the global object node number used in the ID field of all objects.
This routine intializes the global object node number used in the ID field of all objects.
◆ _Objects_MP_Handler_initialization()
void _Objects_MP_Handler_initialization |
( |
void |
| ) |
|
Intializes the inactive global object chain based on the maximum number of global objects configured.
This routine intializes the inactive global object chain based on the maximum number of global objects configured.
◆ _Objects_MP_Is_remote()
Checks if the object identifier is in the global object identifier cache of the specified object information.
- Parameters
-
id | The object identifier. |
information | The object information. |
- Return values
-
true | A remote objects with this object identifier exists in the global object identifier cache of the specified information. |
false | A remote objects with this object identifier does not exist in the global object identifier cache of the specified information. |
◆ _Objects_MP_Open()
Place the specified global object in the specified information table.
This routine place the specified global object in the specified information table.
- Parameters
-
[in,out] | information | Points to the object information table for this object class. |
[in,out] | the_global_object | Points to the object being opened. |
| the_name | The name of the object being opened. |
| the_id | The Id of the object being opened. |
- Todo:
- This method only works for object types with 4 byte object names. It does not support variable length object names.
◆ _Objects_MP_Maximum_global_objects
uint32_t _Objects_MP_Maximum_global_objects |
|
extern |
This is the maximum number of global objects configured.
