uint16_t queue_elem_t::eo

EM EO that this queue belongs to

Definition at line 222 of file em_queue_types.h.

◆ eo_ctx

void* queue_elem_t::eo_ctx

◆ queue

uint32_t queue_elem_t::queue

Queue handle

Definition at line 225 of file em_queue_types.h.

◆ queue_group

em_queue_group_t queue_elem_t::queue_group

Queue group handle of this queue

Definition at line 252 of file em_queue_types.h.

◆ queue_node

list_node_t queue_elem_t::queue_node

◆ valid_check

uint16_t queue_elem_t::valid_check

Check that contents is an EM queue elem.

EM will verify that the ODP queue context actually points to an EM queue elem and not to something else: queue_elem_t *q_elem = odp_queue_context(odp_queue); if (!q_elem || q_elem->valid_check != QUEUE_ELEM_VALID) EM_ERROR(...); Keep first.
