get

Returns one accessible relation target.

Parameters

[in]	targetIndex	0 based index
[out]	target

S_OK
E_INVALIDARG	if bad [in] passed

Use QueryInterface to get IAccessible2.

targets

long IAccessibleRelation::targets([in] long maxTargets, [out, size_is(maxTargets), length_is(*nTargets)] IUnknown targets)

get

Returns multiple accessible relation targets.

Parameters

[in]	maxTargets	maximum size of the array allocated by the client
[out]	targets	The array of target objects. Note that this array is to be allocated by the client and freed when no longer needed. Refer to Special Consideration when using Arrays for more details. You will need to use QueryInterface on the IUnknown to get the IAccessible2.
