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.writeAllFinish to get the result of the operation.

This is the asynchronous version of OutputStream.writeAll.

Call OutputStream.writeAllFinish to collect the result.

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.

Note that no copy of buffer will be made, so it must stay valid until callback is called.

buffer ubyte[]

ioPriority int

the io priority of the request

cancellable Cancellable

optional gio.Cancellable object, NULL to ignore

callback GAsyncReadyCallback
