bool SoundDevice::open (  bool  read,
bool  write
) 
 

open the sound device

Tries to open the sound device for read and/or write if full-duplex is requested but not supported, it returns error and must be called again to fallback on half-duplex mode

Parameters:
read true if device is opened for reading audio
write true if device is opened for writing audio
Returns:
true in case of success, false otherwise

int SoundDevice::write (  void *  buf,
int  len
) 
 

writes audio data from a buffer to the device, len is samples

Definition at line 319 of file dev_sound.cpp.
