+== NAME
+
+nng_aio_abort - abort asynchronous I/O operation
+
+== SYNOPSIS
+
+[source, c]
+-----------
+#include <nng/nng.h>
+
+void nng_aio_abort(nng_aio *aio, int err);
+-----------
+
+
+== DESCRIPTION
+
+The `nng_aio_abort()` function aborts an operation previously started
+with the handle _aio_.  If the operation is aborted, then the callback
+for the handle will be called, and the function
+<<nng_aio_result#,nng_aio_result(3)>> will return the error _err_.
+
+This function does not wait for the operation to be fully aborted, but
+returns immediately.
+
+If no operation is currently in progress (either because it has already
+finished, or no operation has been started yet), then this function
+has no effect.
+
+== RETURN VALUES
+
+None.
+
+== ERRORS
+
+None.
