OSStatus SSpListener_GetTransform (
SSpListenerReference inListenerReference,
TQ3Matrix4x4 *outTransform);

inListenerReference

A listener reference.

outTransform

On exit, a 4-by-4 matrix that specifies the current transformation to be applied to the listener.

function result

A result code.

DESCRIPTION

The SSpListener_GetTransform function returns, in the outTransform parameter, a 4-by-4 matrix that specifies the current transformation to be applied to the position, velocity, orientation, and up vector of the listener specified by the inListenerReference parameter.
