Is there any method to access an integer values from NanoVDB?

[Nord3D]

In CNanoVDB.h I see cnanovdb_readaccessor_getValue##SUFFIX. So, the "SUFFIX", obviosly, indicates data type. But in CVDBUtil.h there are only cnanovdb_readaccessor_getValueF and cnanovdb_readaccessor_getValueF3 for float and float3 values respectively. So, there are no ready-to-use integer types here. I believe this is somehow possible, but since I'm not a professional programmer, it's hard for me to figure it out on my own.
By the way, I'm trying to bind for reading a VDB of type int32 in SideFX Houdini's OpenCL SOP.
