|
* uses the NuttX audio system to play media files read in from the

* Input Parameters:
|

* buf - The user allocated buffer to be filled.

* buflen - the size of the buffer.

* instream - The stream to read characters from
|
|
* outstream - The stream to each characters to.
|
|
*
|
|
* Returned values:
|
|
* On success, the (positive) number of bytes transferred is returned.
