Request an asynchronous read of count bytes from the stream into the buffer starting at buffer.
This is the asynchronous equivalent of gio.input_stream.InputStream.readAll.
Call gio.input_stream.InputStream.readAllFinish 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.
a buffer to read data into (which should be at least count bytes long)
the [I/O priority][io-priority] of the request
optional #GCancellable object, null to ignore
a #GAsyncReadyCallback to call when the request is satisfied
