Detailed Description

Reads and decodes audio data into an usable audio stream for the ISoundEngine.

virtual irrklang::IAudioStream::~IAudioStream (  )  [inline, virtual]

destructor


Member Function Documentation

virtual SAudioStreamFormat irrklang::IAudioStream::getFormat (  )  [pure virtual]

returns format of the audio stream

virtual bool irrklang::IAudioStream::getIsSeekingSupported (  )  [inline, virtual]

returns true if the audio stream is seekable

virtual ik_s32 irrklang::IAudioStream::readFrames ( void *  target,
ik_s32  frameCountToRead 
) [pure virtual]

tells the audio stream to read frameCountToRead audio frames into the specified buffer

Parameters:
target,: Target data buffer to the method will write the read frames into. The specified buffer will be at least getFormat().getFrameSize()*frameCountToRead bytes big.
frameCountToRead,: amount of frames to be read.
Returns:
Returns amount of frames really read. Should be frameCountToRead in most cases.
virtual bool irrklang::IAudioStream::setPosition ( ik_s32  pos  )  [pure virtual]

sets the position of the audio stream.

For example to let the stream be read from the beginning of the file again, setPosition(0) would be called. This is usually done be the sound engine to loop a stream after if has reached the end. Return true if sucessful and 0 if not.

Parameters:
pos,: Position in frames.
