Function Documentation

rte_osadapter_memory_register()

rte_status_t rte_osadapter_memory_register

(

const rte_osadapter_memory_t *

adapter

)

Registers the OSAdapter memory implementation.

Global variables declarations Local function declarations Global functions

Parameters

adapter

Pointer to memory operations vtable.

Returns

RTE_STATUS_OK on success, RTE_STATUS_INVALID_PARAM if adapter is NULL, or RTE_STATUS_INVALID_STATE if the setup phase is already locked (REQ-LIFECYCLE-001, ADR-026; the previous registration, if any, is kept).

REQ-OAL-MEM-014: Follows the OSAdapter-registration contract (ADR-005 section 2.1): a NULL adapter is rejected with RTE_STATUS_INVALID_PARAM; re-registering replaces the previous OSAdapter.
