Implementation details.

Cgo provides a way for Go programs to call C code linked into the same
address space. This comment explains the operation of cgo.

Cgo reads a set of Go source files and looks for statements saying
import "C". If the import has a doc comment, that comment is
taken as literal C code to be used as a preamble to any C code
generated by cgo. A typical preamble #includes necessary definitions:

{* ../../docs_src/path_operation_advanced_configuration/tutorial004.py hl[19:29] *}

## Réponses supplémentaires

Vous avez probablement vu comment déclarer le `response_model` et le `status_code` pour une *opération de chemin*.

Cela définit les métadonnées sur la réponse principale d'une *opération de chemin*.

Ahora creamos una dependencia que devuelve un nuevo `config.Settings()`.

{* ../../docs_src/settings/app02_an_py39/main.py hl[6,12:13] *}

/// tip | Consejo

Hablaremos del `@lru_cache` en un momento.

Por ahora puedes asumir que `get_settings()` es una función normal.

///

Y luego podemos requerirlo desde la *path operation function* como una dependencia y usarlo donde lo necesitemos.

                final String replacedLine = line.replaceAll("#.*$", StringUtil.EMPTY).trim();

                // Skip empty lines or comment lines
                if (replacedLine.length() == 0) {
                    if (updater != null) {
                        updater.write(line);
