iChannelCodeID

Specifies the ChannelCodeID of the channel which attributes should be set.

iVolume

Specifies the volume of the sound the channel produces. Values have to fall in the range [0, 100], with 0 is total silence and 100 is maximum volume. When -1 is specified the current volume value is left untouched, but this is not necessary, just set iWhat to the right value.

iPan

Specifies the panning of the channel in 2D. Values have to fall in the range [-100, 100], with -100 will place the channel totally on the left speaker and 100 will place the channel totally on the right speaker. When -101 is specified the current panning value for this channel is left untouched, but this is not necessary, just set iWhat to the right value.

iFrequency

The frequency of the output of the channel. Values have to fall in the range [100, 100000] with 100 the minimum value and 100000 the maximum value. When 0 is specified the original frequency of the channel when it was created is restored. When -1 is specified, the current value for the frequency is left untouched, but this is not necessary, just set iWhat to the right value. This value is not recommended for DGL_SS_MP3ELEMENT and DGL_SS_MODELEMENT sound element based channels.

iWhat

Specifies what to update of the attributes passed. iWhat is a collection of one or more of these values:

iWhat value	Description
DGL_SS_SA_FREQUENCY	Set frequency with the value in iFrequency
DGL_SS_SA_VOLUME	Set volume with the value in iVolume
DGL_SS_SA_PAN	Set panning with the value in iPan

// Set frequency of channel with id iChannelCodeID to frequency 44100hz and pan
// to the total right.
iResult = DEMOGL_SoundSystemSetChannelAttributes(
		iChannelCodeID, -1, 100, 44100, DGL_SS_SA_FREQUENCY | DGL_SS_SA_PAN);
