How to fill the buffer?

[BeirBear]

Hello

I try to fill the buffer for the application (Stream buffer from the application).
I try to create an application to play MP3 file and able to change sample rate.
I used CMdaAudioOutputStream and I don't know how to fill the buffer.

void CStreamApp::PlayL()
{
if (iState == EReadyToPlay)
{
iAudioStream -> WriteL(aData);
iStatus = EPlaying;
}
}

void CStreamApp::FillBuffer()
{
???
}

Sincerity,
Newbie
(Please help)
