Request an asynchronous write of the data in bytes to the stream.
When the operation is finished callback will be called. You can
then call g_output_stream_write_bytes_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.
A GBytes larger than G_MAXSSIZE will cause a
G_IO_ERROR_INVALID_ARGUMENT error.
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.
For the synchronous, blocking version of this function, see
g_output_stream_write_bytes().
