Detailed Description
Object Attributes Handler.
This encapsulates functionality which defines and manages the set of Classic API object attributes.
This include file contains all information about the Object Attributes Handler.
Macro Definition Documentation
◆ RTEMS_DEFAULT_ATTRIBUTES
| #define RTEMS_DEFAULT_ATTRIBUTES 0x00000000 |
This is the default value for an attribute set.
Referenced by rpcUdpCleanup().
◆ RTEMS_FLOATING_POINT
| #define RTEMS_FLOATING_POINT 0x00000001 |
This attribute constant indicates that the task will use the floating point hardware.
There will be a floating point context associated with this task.
Referenced by _Attributes_Is_floating_point().
◆ RTEMS_INHERIT_PRIORITY
| #define RTEMS_INHERIT_PRIORITY 0x00000040 |
This attribute constant indicates that the Classic API Semaphore instance created will use the Priority Inheritance Protocol.
- Note
- The semaphore instance must be a binary semaphore.
Referenced by _Attributes_Has_at_most_one_protocol(), and _Attributes_Is_inherit_priority().
◆ RTEMS_MULTIPROCESSOR_RESOURCE_SHARING
| #define RTEMS_MULTIPROCESSOR_RESOURCE_SHARING 0x00000100 |
This attribute constant indicates that the Classic API Semaphore instance created will use the Multiprocessor Resource Sharing Protocol.
- Note
- The semaphore instance must be a binary semaphore.
Referenced by _Attributes_Has_at_most_one_protocol(), and _Attributes_Is_multiprocessor_resource_sharing().
◆ RTEMS_NO_FLOATING_POINT
| #define RTEMS_NO_FLOATING_POINT 0x00000000 |
This attribute constant indicates that the task will not use the floating point hardware.
If the architecture permits it, then the FPU will be disabled when the task is executing.
◆ RTEMS_PRIORITY_CEILING
| #define RTEMS_PRIORITY_CEILING 0x00000080 |
This attribute constant indicates that the Classic API Semaphore instance created will use the Priority Ceiling Protocol.
- Note
- The semaphore instance must be a binary semaphore.
Referenced by _Attributes_Has_at_most_one_protocol(), _Attributes_Is_priority_ceiling(), and rtems_semaphore_create().
Typedef Documentation
◆ rtems_attribute
| typedef uint32_t rtems_attribute |
This defines the type used to contain Classic API attributes.
These are primarily used when creating objects.
