Mutex Service - Backend Adaptation

Backend vtable and registration for the Mutex service (ADR-033). More...

Data Structures
struct	sapi_mutex_backend_t
	Backend vtable: an integrator's implementation of the mutex service for a specific OS/RTOS/BSP target (ADR-033). Any slot may be NULL if that operation is unsupported by the backend, in which case the corresponding sapi_mutex_* call returns SAPI_STATUS_NOT_SUPPORTED. More...

Functions
sapi_status_t	sapi_mutex_register_backend (const sapi_mutex_backend_t *backend)
	Registers the backend implementation used by every sapi_mutex_* call. This is how an integrator supplies their own mutex implementation - call once at startup, before any other sapi_mutex_* function.

Detailed Description

Backend vtable and registration for the Mutex service (ADR-033).

Function Documentation

sapi_mutex_register_backend()

sapi_status_t sapi_mutex_register_backend

(

const sapi_mutex_backend_t *

backend

)

Registers the backend implementation used by every sapi_mutex_* call. This is how an integrator supplies their own mutex implementation - call once at startup, before any other sapi_mutex_* function.

Parameters

backend

Must not be NULL. Registering again replaces the previously registered backend.

Returns

SAPI_STATUS_INVALID_PARAM if backend is NULL; SAPI_STATUS_OK otherwise.

SAPI_STATUS_INVALID_STATE if the application's setup phase is already locked (ADR-026).
