Pure C examples for the IoTDB Session C API (SessionC.h): tree model (tree_example) and table model (table_example). Default connection: 127.0.0.1:6667, user root / password root (edit the macros at the top of each .c file).

Using Maven to build this example project (requires Boost, same as the C++ client; on Windows see iotdb-client/client-cpp/README.md):

• cd the root path of the whole project
• run
  mvn package -DskipTests -P with-cpp -pl example/client-c-example -am
  (use mvn clean package ... when no other process holds files under iotdb-client/client-cpp/target; on Windows add Boost paths, e.g.
  -D"boost.include.dir=C:\local\boost_1_87_0" -D"boost.library.dir=C:\local\boost_1_87_0\lib64-msvc-14.2")
• cd example/client-c-example/target

After a successful build you should have:

• Unpacked C++ client headers and libraries under client/ and Thrift under thrift/ (same layout as client-cpp-example)
• CMake-generated binaries, for example on Windows MSVC:
  Release/tree_example.exe, Release/table_example.exe
  (exact path depends on the CMake generator)

Start IoTDB first, then:

# Windows (example)
Release\tree_example.exe
Release\table_example.exe

On failure, the programs print to stderr and you can inspect ts_get_last_error().

example/client-c-example/
+-- README.md
+-- pom.xml
+-- src/
|   +-- CMakeLists.txt
|   +-- tree_example.c
|   +-- table_example.c

The Maven build copies src/*.c and src/CMakeLists.txt into target/ next to the unpacked client/ and thrift/ trees, then runs CMake to compile the two executables.
