Macro Definition Documentation

#define TIVX_OBJ_DESC_DATA_REF_Q_FLAG_DELAY_SLOT_AUTO_AGE (0x00000008u)

Data Ref Q flag to determine if delay slot to which this obj desc belongs should be auto aged.

Valid only when TIVX_OBJ_DESC_DATA_REF_Q_FLAG_IS_IN_DELAY is set

Definition at line 129 of file tivx_obj_desc_priv.h.

tivx_obj_desc_t* ownObjDescAlloc	(	vx_enum	type,
		vx_reference	ref
	)

Allocate a Object descriptor.

Parameters

type	[in] Type of object descriptor to allocate, see tivx_obj_desc_type_e
ref	[in] vx_reference that is associated with this object descriptor. If not applicable set to NULL

Returns: Pointer tivx_obj_desc_t on success; NULL, if object descriptor could not be allocated

vx_status ownObjDescFree ( tivx_obj_desc_t ** obj_desc )

Free a previously allocated object descriptor.

Parameters

[in] obj_desc Object descriptor to free

Sends a object descriptor to specified target.

The API does not wait for ACK. ACK handling if any is done by user The API may result in a IPC is target is on another CPU

Source target ID is not required since ACK is not handled by this API

Parameters

[in]	dst_target_id	Destination target ID
[in]	obj_desc_id	Object descriptor ID

tivx_obj_desc_t* ownObjDescGet ( uint16_t obj_desc_id )

Get obj descriptor corresponding to the object descriptor ID.

If obj_desc_id is invalid or out of bounds NULL is returned.

Parameters

[in] obj_desc_id Object descriptor ID
