SYNOPSIS

+
+
+
+
#include <nng/nng.h>
+
+size_t nng_aio_count(nng_aio *aio);
+
+
+
+
+
+

DESCRIPTION

+
+
+

The nng_aio_count() returns the number of bytes transferred by the +asynchronous operation associated with the handle aio.

+
+
+

Some asynchronous operations do not provide meaningful data for this +function; for example operations that establish connections do not +transfer user data (they may transfer protocol data though) — in this case +this function will generally return zero.

+
+
+

This function is most useful when used with operations that make use of +of a scatter/gather vector (set by nng_aio_set_iov()).

+
+
+ + + + + +
+ + +The return value from this function is undefined if the operation +has not completed yet. +Either call this from the handle’s completion callback, +or after waiting for the operation to complete with +nng_aio_wait(). +
+
+
+
+
+

RETURN VALUES

+
+
+

The number of bytes transferred by the operation.

+
+
+
+
+

ERRORS

+
+
+

None.
