+== NAME
+
+nng_aio_free - free asynchronous I/O handle
+
+== SYNOPSIS
+
+[source, c]
+-----------
+#include <nng/nng.h>
+
+void nng_aio_free(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 <<nng_aio_stop#,nng_aio_stop(3)>>.)
+
+== RETURN VALUES
+
+None.
+
+== ERRORS
+
+None.
