+== NAME
+
+nng_aio_set_input - return input parameter
+
+== SYNOPSIS
+
+[source, c]
+-----------
+#include <nng/nng.h>
+
+void *nng_aio_get_input(nng_aio *aio, unsigned int index);
+-----------
+
+== DESCRIPTION
+
+The `nng_aio_get_input()` function returns the value of the input parameter
+previously set at _index_ on _aio_ with the
+<<nng_aio_set_input#,nng_aio_set_input(3)>> function.
+
+The valid values of _index_ range from zero (0) to three (3), as no operation
+currently defined can accept more than four parameters.  (This limit could
+increase in the future.)  If the index supplied is outside of this range,
+or of the input parameter was not previously set, then `NULL` is returned.
+
+== RETURN VALUES
+
+Value previously set, or `NULL`.
+
+== ERRORS
+
+None.
