-A public method which sets a user-defined callback function for a given stream.
-<p>
-This method assigns a callback function to a specific, previously opened stream for non-blocking stream functionality. A separate process is initiated, though the user function is called only when the stream is "running" (between calls to the <a class="el" href="classRtAudio.html#a11">startStream</a>() and <a class="el" href="classRtAudio.html#a12">stopStream</a>() methods, respectively). The callback process remains active for the duration of the stream and is automatically shutdown when the stream is closed (via the <a class="el" href="classRtAudio.html#a10">closeStream</a>() method or by object destruction). The callback process can also be shutdown and the user function de-referenced through an explicit call to the <a class="el" href="classRtAudio.html#a5">cancelStreamCallback</a>() method. Note that a single stream can use only blocking or callback functionality at the same time, though it is possible to alternate modes on the same stream through the use of the <a class="el" href="classRtAudio.html#a4">setStreamCallback</a>() and <a class="el" href="classRtAudio.html#a5">cancelStreamCallback</a>() methods (the blocking <a class="el" href="classRtAudio.html#a9">tickStream</a>() method can be used before a callback is set and/or after a callback is cancelled).
