Method Detail

close

public int close()

Calls snd_mixer_close().

readControlList

public int readControlList(int[] anIndices,
                  java.lang.String[] astrNames)

The caller has to allocate the indices and names arrays big enough to hold information on all controls. If the retrieving of controls is successful, a positive number (the number of controls) is returned. If the arrays are not big enough, -1 is returned. In this case, it's the task of the caller to allocate bigger arrays and try again. Both arrays must be of the same size. Calls snd_mixer_first_elem() and snd_mixer_elem_next().

setTrace

public static void setTrace(boolean bTrace)
