# Additional Status Codes

By default, **FastAPI** will return the responses using a `JSONResponse`, putting the content you return from your *path operation* inside of that `JSONResponse`.

It will use the default status code or the one you set in your *path operation*.

## Additional status codes

func (fi headerFileInfo) Sys() any           { return fi.h }

// Name returns the base name of the file.
func (fi headerFileInfo) Name() string {
	if fi.IsDir() {
		return path.Base(path.Clean(fi.h.Name))
	}
	return path.Base(fi.h.Name)
}

// Mode returns the permission and mode bits for the headerFileInfo.
func (fi headerFileInfo) Mode() (mode fs.FileMode) {
	// Set file permission bits.

Details about the `async def` syntax for *path operation functions* and some background about asynchronous code, concurrency, and parallelism.

## In a hurry?

<abbr title="too long; didn't read"><strong>TL;DR:</strong></abbr>

If you are using third party libraries that tell you to call them with `await`, like:

```Python
results = await some_library()
```

Then, declare your *path operation functions* with `async def` like:

set FESS_PARAMS=-Dfess;-Dfess.home="%FESS_HOME%";-Dfess.es.dir="%SEARCH_ENGINE_HOME%";-Dfess.home="%FESS_HOME%";-Dfess.context.path="/";-Dfess.port=8080;-Dfess.webapp.path="%FESS_HOME%\app";-Dfess.temp.path="%FESS_HOME%\temp";-Dfess.log.name="%APP_NAME%";-Dfess.log.path="%FESS_HOME%\logs";-Dfess.log.level=warn;-Dlasta.env=web;-Dtomcat.config.path=tomcat_config.properties
