Detailed Description

This group contains the Classic API directive attributes.

Macro Definition Documentation

◆ RTEMS_FLOATING_POINT

#define RTEMS_FLOATING_POINT 0x00000001

This attribute constant indicates that the Classic API task created by rtems_task_create() or rtems_task_construct() shall be able to use the floating point hardware.

Notes: On some architectures, there will be a floating point context associated with this task.

◆ RTEMS_GLOBAL

#define RTEMS_GLOBAL 0x00000002

This attribute constant indicates that the Classic API object shall be a global resource in a multiprocessing network.

Notes: This attribute does not refer to SMP systems.

◆ RTEMS_INHERIT_PRIORITY

#define RTEMS_INHERIT_PRIORITY 0x00000040

This attribute constant indicates that the Classic API semaphore created by rtems_semaphore_create() shall use the Priority Inheritance Protocol.

Notes: The semaphore shall be a binary semaphore (RTEMS_BINARY_SEMAPHORE).

◆ RTEMS_LOCAL

#define RTEMS_LOCAL 0x00000000

This attribute constant indicates that the Classic API object shall be a local resource in a multiprocessing network.

Notes: This attribute does not refer to SMP systems.

◆ RTEMS_MULTIPROCESSOR_RESOURCE_SHARING

#define RTEMS_MULTIPROCESSOR_RESOURCE_SHARING 0x00000100

This attribute constant indicates that the Classic API semaphore created by rtems_semaphore_create() shall use the Multiprocessor Resource Sharing Protocol.

Notes: The semaphore shall be a binary semaphore (RTEMS_BINARY_SEMAPHORE).

Notes: 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 created by rtems_semaphore_create() shall use the Priority Ceiling Protocol.

Notes: The semaphore shall be a binary semaphore (RTEMS_BINARY_SEMAPHORE).
