#include <nn/jpeg.h>

static const u8 * GetGpsProcessingMethodPointer(
     const GpsData * pGps
);

	Name	Description
in	pGps	Specifies the GPS IFD. Call the GetLastGpsData function to obtain this.

If successful, the function returns a pointer to the name of the position location method. Returns NULL on failure.

This function needs image data to get the information. Do not destroy the GPS IFD structure.

This data (text string) does not end in zero. Use the GetGpsProcessingMethodSize function to get the size of data in bytes. If the size of the the data is 0 bytes, both that function and this function fail.
