Function Documentation

◆ ownIsValidContext()

vx_bool ownIsValidContext ( vx_context context )

Check if 'context' is valid.

Parameters

[in] context The reference to context

Returns: A vx_status_e enumeration.

Return values

VX_SUCCESS No errors.

◆ ownContextFlushCmdPendQueue()

vx_status ownContextFlushCmdPendQueue ( vx_context context )

Flushes the command pend queue, if not empty.

Parameters

[in] context The reference to context

Returns: A vx_status_e enumeration.

Return values

VX_SUCCESS No errors.

◆ ownAddReferenceToContext()

vx_bool ownAddReferenceToContext	(	vx_context	context,
		vx_reference	ref
	)

Add reference to a context.

Parameters

[in]	context	The overall context.
[in]	ref	The reference to add.

Returns: vx_true_e on success; vx_false_e on failure

◆ ownRemoveReferenceFromContext()

vx_bool ownRemoveReferenceFromContext	(	vx_context	context,
		vx_reference	ref
	)

Remove reference from a context.

Parameters

[in]	context	The overall context.
[in]	ref	The reference to remove.

Returns: vx_true_e on success; vx_false_e on failure

◆ ownAddKernelToContext()

vx_status ownAddKernelToContext	(	vx_context	context,
		vx_kernel	kernel
	)

Add's unique kernel to context.

Increment internal reference count of the kernel

◆ ownRemoveKernelFromContext()

vx_status ownRemoveKernelFromContext	(	vx_context	context,
		vx_kernel	kernel
	)

Remove unique kernel from context.

Decrement internal reference count of the kernel

◆ ownContextSendCmd()

vx_status ownContextSendCmd	(	vx_context	context,
		uint32_t	target_id,
		uint32_t	cmd,
		uint32_t	num_obj_desc,
		const uint16_t *	obj_desc_id,
		uint32_t	timeout
	)

Send a command to specified target with object descriptor ID's as parameters.

This API waits until ACK for the command is received

Parameters

context	[in] context to use when sending the command
target_id	[in] ID of Target to whom the command is being sent
cmd	[in] command to send
num_obj_desc	[in] number of object descriptors to send
obj_desc_id	[in] List of object descriptor to send
timeout	[in] Timeout in units of msecs, use TIVX_EVENT_TIMEOUT_WAIT_FOREVER to wait forever

◆ ownContextSendControlCmd()

vx_status ownContextSendControlCmd	(	vx_context	context,
		uint16_t	node_obj_desc,
		uint32_t	target_id,
		uint32_t	replicated_node_idx,
		uint32_t	node_cmd_id,
		const uint16_t	obj_desc_id[],
		uint32_t	num_obj_desc,
		uint32_t	timeout
	)

Send a control command to specified target with object descriptor ID's as parameters.

This API waits for 'timeout' msecs, until ACK for the command is received

Parameters

context	[in] context to use when sending the command
node_obj_desc	[in] ID of node object descriptor to which command is being sent
target_id	[in] ID of Target to whom the command is being sent
replicated_node_idx	[in] If the node is replicated, index of the replicant to send the command to
node_cmd_id	[in] ID of the command to send to the node
obj_desc_id[]	[in] Array of IDs of object descriptor
num_obj_desc	[in] Number of object descriptors in obj_desc_id[] array
timeout	[in] Timeout in units of msecs, use TIVX_EVENT_TIMEOUT_WAIT_FOREVER to wait forever

◆ ownContextGetKernelRemoveLock()

vx_bool ownContextGetKernelRemoveLock ( vx_context context )

Get value of kernel remove lock flag.

Parameters

context [in] context

◆ ownContextSetKernelRemoveLock()

void ownContextSetKernelRemoveLock	(	vx_context	context,
		vx_bool	do_lock
	)

Set value of kernel remove lock flag.

Parameters

context	[in] context
do_lock	[in] kernel remove lock value to set

◆ ownContextLock()

vx_status ownContextLock ( vx_context context )

Lock context.

Parameters

context [in] context

◆ ownContextUnlock()

vx_status ownContextUnlock ( vx_context context )

Lock context.

Parameters

context [in] context

◆ ownGetContext()

vx_context ownGetContext ( void )

Returns the vx_context object currently being used.

This API returns the context being used. If the context has not yet been created using vxCreateContext, then it returns NULL. This API does not include reference counting like in the vxCreateContext.

Returns: The vx_context object being used.
