Request an asynchronous write of count bytes from buffer into
the stream. When the operation is finished callback will be called.
You can then call OutputStream.writeFinish 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 value of count 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.
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
OutputStream.write.
Note that no copy of buffer will be made, so it must stay valid
until callback is called. See OutputStream.writeBytesAsync
for a glib.Bytes version that will automatically hold a reference to
the contents (without copying) for the duration of the call.
