nng_stream_send(3str)
NAME
nng_stream_send - send to byte stream
SYNOPSIS
DESCRIPTION
The nng_stream_send() function starts an asynchronous send over the
byte stream s
from 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
sent, or an error has occurred.
Therefore, the number of bytes sent may be less than requested.
The actual number of bytes sent can be determined with
nng_aio_count().
RETURN VALUES
None.
ERRORS
NNG_ECANCELED
|
The operation was canceled. |
NNG_ECLOSED
|
The connection was closed. |
NNG_ECONNRESET
|
The peer closed the connection. |
NNG_EINVAL
|
The aio does not contain a valid scatter/gather vector. |
NNG_ENOMEM
|
Insufficient free memory to perform the operation. |
NNG_ETIMEDOUT
|
Timeout waiting for data from the connection. |
