Data Structures
struct	rte_task_config_t
	Configuration for rte_task_create(). More...

Typedefs
typedef struct rte_task_impl_s *	rte_task_handle_t
	Opaque handle to a created task, returned by rte_task_create().
typedef void(*)	rte_task_entry_t(void *user_ctx)
	Task entry point, invoked cyclically at the configured period.

Functions
	RTE_DECLARE_STORAGE (rte_task_storage_t, 128U)
	Caller-owned, fixed-size storage backing one rte_task_handle_t.
rte_status_t	rte_task_create (rte_task_storage_t *storage, const rte_task_config_t *config, rte_task_handle_t *out_handle)
	Creates a task in the suspended state.
rte_status_t	rte_task_start (rte_task_handle_t handle)
	Starts a created task.
rte_status_t	rte_task_suspend (rte_task_handle_t handle)
	Suspends a running task.
rte_status_t	rte_task_destroy (rte_task_handle_t handle)
	Terminates and destroys a task.

Detailed Description

OS Abstraction Layer - Task/thread scheduling service.

Creation of periodic/cyclic safety tasks with fixed priorities, matching the cyclic processing model typical of RBC implementations. See ADR-001.

REQ-OAL-TASK-001: no dynamic allocation; caller supplies storage and a fixed-size stack/context region (osadapter-defined use). REQ-OAL-TASK-002: priorities are fixed at creation time; no dynamic priority inheritance/inversion handling is assumed by this API - that is an OSAdapter/RTOS concern.
