GetNextLidarQueryPoints
=======================

.. currentmodule:: globalmapper
.. py:function:: GetNextLidarQueryPoints (GM_LidarQueryHandle_t aLidarQuery, GM_LidarPoint_t aPointList, uint32 aListSize, GM_GetFeatureFlags_t32 aFlags, uint32 aReserved=0) -> GM_Error_t32, uint32

    Retrieves the next block of points from the Lidar query. You should repeatedly call this function to iterate through
    all of the points matching the original Lidar query from the :doc:`CreateLidarQuery<globalmapper.CreateLidarQuery>`
    call. The returned uint32 value will match the *aListSize* value until you reach the end of the points.

    :param GM_LidarQueryHandle_t aLidarQuery: Lidar query to get data from
    :param GM_LidarPoint_array aPointList: (In/Out) Lidar point(s) to fill in
    :param uint32 aListSize:  Max number of points to fetch
    :param GM_GetFeatureFlags_t32 aFlags: Flags for fetching Lidar point
    :param uint32 aReserved: Reserved for future use; defaults to 0
    :returns: Error Code
    :rtype: GM_Error_t32
    :return: Number of points actually read
    :rtype: uint32
