DuckDB C API Headers

This directory contains the C API headers of DuckDB. These headers should generally match the TARGET_DUCKDB_VERSION that is specified in the Makefile. Note that these headers can be updated automatically to match the TARGET_DUCKDB_VERSION makefile variable by running (assuming the default makefile setup):

make update_duckdb_headers

Of course manually updating the headers is also fine, just make sure that the headers are always from the same DuckDB version and that they are not from a later release of DuckDB than is specified in the TARGET_DUCKDB_VERSION build variable. Using headers from an older version than TARGET_DUCKDB_VERSION is allowed, but you probably don't want that.
