#include "ltvkrn.h"

L_LVKRN_API L_INT L_VecGetHitTest(pVector, pHitTest)

Gets the current hit test settings.

Parameters

const pVECTORHANDLE pVector

Pointer to a vector handle.

pVECTORHITTEST pHitTest

Pointer to a VECTORHITTEST structure to be updated with the current hit test settings.

Returns

Comments

The hit test settings determine the behavior of the hit test. The hit test itself is performed by calling L_VecHitTest.

The hit test settings can be changed by calling L_VecSetHitTest.

For more information on possible hit test settings, refer to the VECTORHITTEST structure.
