- Description
The TDx_SoundBuffer::Unlock method will release the sound buffer area previously locked by TDx_SoundBuffer::Lock().
Both pointers and both byte values returned by TDx_SoundBuffer::Lock() must be supplied, even if 0 bytes were written to the second pointer.
Do not lock the sound buffer for long periods of time as the play cursor could reach the locked bytes and configuration dependent audio problems may result.
If the method call fails, the OnError event will be triggered with one of the following values:
TDX_BADPARAMS
DSERR_INVALIDCALL
DSERR_INVALIDPARAM
DSERR_PRIOLEVELNEEDED
- Parameters
AudioPtr1
The AudioPtr1parameter should reference the value returned in the AudioPtr1 parameter of TDx_SoundBuffer::Lock().
AudioBytes1
The AudioBytes1 parameter defines the number of bytes written to the area referenced by the AudioPtr1 parameter.
AudioPtr2
The AudioPtr2 parameter should reference the value returned in the AudioPtr2 parameter of TDx_SoundBuffer::Lock().
AudioBytes2
The AudioBytes2 parameter defines the number of bytes written to the area referenced by the AudioPtr2 parameter.
