Detailed Description

OSS implementation of the Sound Wrapper.

This wrapper reads the header of a wav file, then it tries to set the values and simply writes to the dsp device.

Constructor & Destructor Documentation

CSndWrapOSS()

CSndWrapOSS::CSndWrapOSS ( const eC_String &  kDevicePath, const eC_UInt  uiStackSize, const ThreadPriority_t  kThreadPriority  )

protected

Constructor

Parameters

kDevicePath	The dsp device path.
uiStackSize	The play sound thread stack size.
kThreadPriority	The play sound thread priority.

Member Function Documentation

CreateInstance()

static void CSndWrapOSS::CreateInstance ( const eC_String &  kDevicePath = "/dev/dsp", const eC_UInt  uiStackSize = 100, const ThreadPriority_t  kThreadPriority = GUITHREAD_PRIORITY_NOT_SET  )

static

Creates the OSS sound wrapper instance.

Parameters

kDevicePath	The dsp device path.
uiStackSize	The play sound thread stack size.
kThreadPriority	The play sound thread priority.

GetVolume()

eC_UByte CSndWrapOSS::GetVolume ( )

virtual

Method to get the volume of an output device. The volume has to be implemented in percent. The range is from 0 till 100.

Returns

The currently set volume in percent.

Implements CSndWrapLinux.

SetVolume()

eC_Bool CSndWrapOSS::SetVolume ( eC_UByte  ubVolume = 0xff )

virtual

Method to set the volume of an output device. The volume has to be implemented in percent. The range is from 0 till 100.

Parameters

ubVolume

to set in percent.

Returns

False on error.

Implements CSndWrapLinux.

UnloadSnd()

void CSndWrapOSS::UnloadSnd ( const SoundResource_t &  eID )

virtual

Method to unload a sound file.

Parameters

eID	ID of the sound to unload.

Reimplemented from CSndWrapLinux.
