Member Function Documentation

void Platform_Win32_Sound_SoundStream_DSound::Play ( ) [virtual]

Starts playing the sound stream, from whatever position it is currently at. The stream will keep playing and loop when it's reached the end, until the Stop method is called. The GetPosition method can be called to monitor the current position in the stream, and if looping is not desired, Stop should be called when the position have reached the end of the stream buffer.

Implements Platform_Sound_SoundStream.

Definition at line 67 of file Platform_Win32_Sound_SoundStream_DSound.cpp.

void Platform_Win32_Sound_SoundStream_DSound::Stop ( ) [virtual]

Pause the playback, and keeps the position so that the next call to Play will resume from the last point.

Implements Platform_Sound_SoundStream.

Definition at line 78 of file Platform_Win32_Sound_SoundStream_DSound.cpp.

int Platform_Win32_Sound_SoundStream_DSound::GetPosition ( ) [virtual]

Retrieves the current position in the sound stream buffer of the playback.

Returns:: The current position

Implements Platform_Sound_SoundStream.

Definition at line 89 of file Platform_Win32_Sound_SoundStream_DSound.cpp.

void Platform_Win32_Sound_SoundStream_DSound::SetPosition ( int position ) [virtual]

Sets the playback position. Must be in the range from 0 to the size of the sound stream buffer. There is no need to call Stop/Play for it to take effect.

Implements Platform_Sound_SoundStream.

Definition at line 102 of file Platform_Win32_Sound_SoundStream_DSound.cpp.

void Platform_Win32_Sound_SoundStream_DSound::CopySoundToBuffer	(	int	bufferOffset,
		const void *	soundData,
		int	bytesToCopy
	)			`[virtual]`

Copies raw sound data to the sound streams buffer, starting at bufferOffset. The data is copied from the soundData pointer, for a total of bytesToCopy number of bytes. bufferOffset + bytesToClear should be less than the value returned by GetSize. The format of the data is interleaved raw sound samples, as specified by the combination of channels, frequency and bits per sample.

Implements Platform_Sound_SoundStream.

Definition at line 113 of file Platform_Win32_Sound_SoundStream_DSound.cpp.

void Platform_Win32_Sound_SoundStream_DSound::ClearBuffer	(	int	bufferOffset,
		int	bytesToClear
	)			`[virtual]`

Clears the specified part of the sound streams buffer. bufferOffset + bytesToClear should be less than the value returned by GetSize

Implements Platform_Sound_SoundStream.

Definition at line 154 of file Platform_Win32_Sound_SoundStream_DSound.cpp.

int Platform_Win32_Sound_SoundStream_DSound::GetChannels ( ) [virtual]

Retrieves the number of channels this sound stream was created with.

Returns:: The number of channels, 1=mono, 2=stereo

Implements Platform_Sound_SoundStream.

Definition at line 193 of file Platform_Win32_Sound_SoundStream_DSound.cpp.

int Platform_Win32_Sound_SoundStream_DSound::GetFrequency ( ) [virtual]

Retrieves the frequency (samples per second) this sound stream was created with. Typical values for this is 11025 (11 kHz), 22050 (22 kHz) or 44100 (44 kHz, CD-quality).
