Hi Jiaqi,
There is yet no detailed documentation on the classes and usage of the
C++ API. However, the source code in tools/src is a great place to learn
how to use the library. In particular, look at the following utilities:
* FileScan.cc reads an ORC file and counts the number of rows and stripes
* FileContents.cc expands the above functionality and print the contents
of an ORC file in JSON format
* FileStatistics.cc reads and displays column statistics at the file-
and stripe-level granularity.
* FileMemory.cc evaluates dynamic memory usage. It also shows how to
read only specific columns from an ORC file.
I hope this is helpful.
Best regards,
Aliaksei.

Dear team,
Now I am trying to use orcfile c++ library to parse orc files, are
there any user guide or instructions to use it? Now I only see the
instructions to compile the library, but I am confused about using it.
For example, if I want to create my source code and call the functions
of the library, how should I do that?
Thanks!
