The application-layer must block on writing I/O. We can't return from a write until we've pushed its bytes onto the socket. Otherwise, if the write fails we are unable to deliver its IOException to the application. We would have told the application layer that the write succeeded, but it didn't!

If xxx is data, cgo arranges for C.xxx to refer to the C variable,
with the type translated as described above.  To do this, cgo must
introduce a Go variable that points at the C variable (the linker can
be told to initialize this pointer).  For example, if the gmp library
provided

	mpz_t zero;

then cgo would rewrite a reference to C.zero by introducing

	var _C_zero *C.mpz_t

			// then we will just fail to add the pod to the mesh, and it will be retried later when cni plugin adds it.

			// We need a pod IP - if the pod was added via the CNI plugin, that plugin told us the IPs
			// for the pod. If this is a pod added via informer, the pod should have already gone thru
			// the CNI plugin chain, and have a PodIP.
			//
			// If PodIPs exists, it is preferred, otherwise fallback to PodIP.

## Use `Annotated` in the type for the `q` parameter

Remember I told you before that `Annotated` can be used to add metadata to your parameters in the [Python Types Intro](../python-types.md#type-hints-with-metadata-annotations){.internal-link target=_blank}?

Now it's the time to use it with FastAPI. 🚀
