The function in Listing 3-10 is the callback function shown in Figure 3-2 and attached to the audio queue in Listing 3-9. The purpose of this function is to read data from the audio file into a buffer and then add it to the audio queue. Or if no more data is available (as indicated by the value returned by AudioFileReadPackets in its numPackets argument), arrange to stop playback. Data is read using the second part of Core Audio s file API, AudioFileReadPackets().

two bodies could be approximated by second-degree surfaces. For such bodies, the contact area was found to be an ellipse. Reference [36.3] contains a comprehensive bibliography. As indicated in Fig. 36.11, there are four special cases in which the contact area is a circle. For these four cases, the maximum pressure occurs at the center of the contact area and is po = 3F 2 a2 (36.44)

where a = the radius of the contact area and F = the normal force pressing the two bodies together. In Fig. 36.11, the x and y axes are in the plane of the contact area and the z axis is normal to this plane. The maximum stresses occur on this axis, they are principal stresses, and their values for all four cases in Fig. 36.11 are

The callback function also illustrates a way of bridging the gap back to the audio playback class. Since you previously called AudioQueueNewOutput with self as the callback function argument, a reference to the object is passed to the callback as userData. By typecasting this to a pointer to the audio playback class, it s possible to make Objective-C method calls to that object from the C callback function. This is why it was important to have getter and setter methods (even synthesized ones) for some of the instance variables declared in Listing 3-8. In this callback, you need to be able to access these variables from outside the scope of the class interface. Listing 3-11 shows the utility function used to determine buffer size in the play method.
