Request an asynchronous write of the bytes contained in @n_vectors @vectors into
the stream. When the operation is finished @callback will be called.
You can then call g_output_stream_writev_finish() to get the result of the
operation.
During an async request no other sync and async calls are allowed,
and will result in %G_IO_ERROR_PENDING errors.
On success, the number of bytes written will be passed to the
@callback. It is not an error if this is not the same as the
requested size, as it can happen e.g. on a partial I/O error,
but generally we try to write as many bytes as requested.
You are guaranteed that this method will never fail with
%G_IO_ERROR_WOULD_BLOCK — if @stream can't accept more data, the
method will just wait until this changes.
Any outstanding I/O request with higher priority (lower numerical
value) will be executed before an outstanding request with lower
priority. Default priority is %G_PRIORITY_DEFAULT.
The asynchronous methods have a default fallback that uses threads
to implement asynchronicity, so they are optional for inheriting
classes. However, if you override one you must override all.
For the synchronous, blocking version of this function, see
g_output_stream_writev().
Note that no copy of @vectors will be made, so it must stay valid
until @callback is called.
