Description

ProfileSystem demonstrates the use of the system_profiler shell command and how it can be called by a Core Foundation application to retrieve the same information that is displayed in the System Profiler utility. The sample uses the UNIX popen call to open a stream and read the results of the system_profiler command. The resultant data is then read into a buffer and converted to a CFArray using the CFPropertyListCreateFromXMLData call. For this sample, the CFArray is then parsed for specific information about PCI and USB devices.
