This file provides an interface "glue" to the underlying PTP implementation from libgphoto2. It uses some local code to convert from/to UTF-8 (stored in unicode.c/.h) and some small utility functions, mainly for debugging (stored in util.c/.h).

The three PTP files (ptp.c, ptp.h and ptp-pack.c) are plain copied from the libhphoto2 codebase.

The files libusb-glue.c/.h are just what they say: an interface to libusb for the actual, physical USB traffic.

## Typedef Documentation

typedef struct _MTPDataHandler MTPDataHandler

These are to wrap the get/put handlers to convert from the MTP types to PTP types in a reliable way

## Function Documentation

void ptp_nikon_getptpipguid | ( | unsigned char * | guid | ) |

Dummy function needed to interface to upstream ptp.c/ptp.h files.
