  * SYNOPSIS
  *

  *
  * DESCRIPTION
  *
  *    Set a notifier callback for the stream indicated by `stream' to be called
- *    when some action takes place on the stream.  It is called for example
- *    when data is available for reading or writing, or if an error occurs.
- *    This can be called at any time for valid stream.  If `notifier' is set
- *    to NULL no callback will be called for the stream.
+ *    when some action takes place on the stream.  This effectively means
+ *    scheduling the stream for various actions, that then eventually will
+ *    be delivered to caller in the `notifier'  callback.  It is called for
+ *    example when data is available for reading or writing, or if an error
+ *    occurs.  This can be called at any time for valid stream.
+ *    If `notifier' is set to NULL no callback will be called for the stream,
+ *    and the stream is not scheduled anymore.
