# c-api/.clang-tidy
# Place this file at the root of whatever directory holds your Part II
# (C API) surface — e.g. c-api/, public-include/, or wherever your extern "C"
# headers and shims live. clang-tidy always uses the closest .clang-tidy file
# up the directory tree, so files under this directory pick up these
# snake_case naming rules instead of the PascalCase/camelCase rules in the
# repo-root .clang-tidy, without any extra flags or per-file configuration.
#
# Formatting (tabs, Allman braces, line length) still comes from the single
# root-level .clang-format — only naming differs between Part I and Part II,
# per style guide §15 (Indentation and Braces).

  # casing; the prefix itself is a code-review convention (see TOOLING.md).
