L_LVKRN_API L_UINT32 L_VecGetObjectTooltip(pVector, pObject, pBuffer, uSize)
Retrieves the tooltip of a vector object.
Pointer to the vector handle.
Pointer to the VECTOROBJECT structure that contains the vector object for which to get the tooltip.
Pointer to a buffer to be updated with the specified object's tooltip.
Size of the buffer allocated for pBuffer.
If pBuffer is NULL, it will return the size of the buffer required for the tooltip string. If pBuffer is not NULL, it will return the number of bytes actually written to the buffer.
