libisofs interprets and manipulates ISO 9660 directory trees. It generates
|
|
|
|
|
the output stream which is handed over to libburn.
|
|
|
|
|
|
|
|
|
|
libisoburn encapsulates the connectivity issues between libburn and
|
|

|

libisofs. It also enables multi-session emulation on overwritable media
|

and random access file objects.

xorriso is intended as reference application of libisoburn.

libisoburn by its lower level API encapsulates the connectivity issues
|
|
|
|

between libburn and libisofs. This API also enables multi-session emulation

on overwritable media and random access file objects.

xorriso is the higher level API of libisoburn which allows to operate all
|
|
|
|
|
three libraries by a unified set of commands.
|
|
|
|
|
xorriso.h exposes the public functions.
|
|
|
|
|
Among these functions are direct equivalents of the xorriso interpreter
|
|
|
|
|
commands. There are also functions for fundamental management and for
|
|
|
|
|
handling event messages.

This file xorriso_main.c runs the xorriso API as batch and dialog program.

xorriso.h exposes the public functions of xorriso which are intended
|
|
|
|

to be used by programs which link with xorriso.o. These functions are
|
|
|
|
|
direct equivalents of the xorriso interpreter commands.
|
|
|
|
|
There is also the API for handling event messages.
|
|
|
|
|
One should not mix the use of the xorriso API with the use of the lower
|
|
|
|
|
level APIs of libburn, libisofs, libisoburn.
