## nng_aio_free
Free asynchronous I/O handle.
### Synopsis
```c
#include <nng/nng.h>
void nng_aio_free(nng_aio *aio);
void nng_aio_reap(nng_aio *aio);
```
### Description
The `nng_aio_free` function frees an allocated asynchronous I/O handle.
If any operation is in progress, the operation is canceled, and the caller is blocked until the operation is completely canceled, to ensure that it is safe to deallocate the handle and any associated resources.
(This is done by implicitly calling xref:nng_aio_stop.adoc[`nng_aio_stop`].)
The `nng_aio_reap` function is the same as `nng_aio_free`, but does its work in a background thread.
This can be useful to discard the _aio_ object from within the callback for the _aio_.
IMPORTANT: Once either of these functions are called, the _aio_ object is invalid and must not be used again.
