SYNOPSIS
#include <nng/nng.h>
void nng_stream_recv(nng_stream *s, nng_aio *aio);DESCRIPTION
The nng_stream_recv() function starts an asynchronous receive from the
byte stream s
into the scatter/gather vector located in the
asynchronous I/O structure aio.
The
nng_aio_set_iov() function must have been
called first, to set the scatter/gather vector for aio.
|
This function returns immediately, with no return value.
Completion of the operation is signaled via the aio,
and the final result may be obtained via
nng_aio_result().
That result will either be zero or an error code.
The I/O operation completes as soon as at least one byte has been
received, or an error has occurred.
Therefore, the number of bytes read may be less than requested.
The actual number of bytes read can be determined with
nng_aio_count().
RETURN VALUES
None.
