gpsapi.dll is backing?

            


I see wm GPS example 5.0 SDK inner tube, which has the following lines of code
#region PInvokes to gpsapi.dll
[DllImport ("gpsapi.dll")]
static extern IntPtr GPSOpenDevice (IntPtr hNewLocationData, IntPtr hDeviceStateChange, string szDeviceName, int dwFlags);
But I can not find this file in the hard disk, the program can be run, Editor's Note enjoin

gpsapi.dll did not find the machine, but I think this is Microsoft to help you sealed an API, SDK may come from inside gpsapi.h it.
