/* xorriso - libisoburn higher level API which creates, loads, manipulates
             and burns ISO 9660 filesystem images.

   Copyright 2007-2015 Thomas Schmitt, <scdbackup@gmx.net>

   Provided under GPL version 2 or later.

   This file contains the public API of xorriso which covers all of its
   operations.

   An example of its usage is xorriso_main.c which checks version compatibility,
   creates a xorriso object, initializes the libraries, and runs the command
   interpreters of the API to constitute the command line oriented batch and
   dialog tool xorriso.

   Alternatively to command interpreters it is possible to run all options of
   xorriso directly via the calls of the "Command API". 
   The "Problem Status and Message API" shall then be used to obtain the
   text output of the options.

   Mandatory calls are:
     Xorriso_new(), Xorriso_startup_libraries(), Xorriso_destroy()

   This architecture is fully public since version 0.5.8. From then on, new
   features get marked by
     @since major.minor.micro
   If this mark is missing, then the feature was present before release 0.5.8.

   Please note that struct XorrisO and its API calls are _not_ thread-safe in
   general. It is not permissible to run two API calls on the same
   XorrisO object concurrently.
   The only exception is
     Xorriso_fetch_outlists()
   in order to learn about the ongoing text output of other API calls.


   There is a lower level of API which consists of libisofs.h, libburn.h and
   libisoburn.h. One should not mix those calls with the ones of xorriso.h .

    Better do not base the fundamental compatibility decision of an application

    @since 0.5.8
    @param major The maturity version (0 for now, as we are still learning)
    @param minor The development goal version.
    @param micro The development step version. This has an additional meaning:

                 Pare numbers indicate a version with frozen API. I.e. you can
                 rely on the same set of features to be present in all
                 published releases with that major.minor.micro combination.
                 Features of a pare release will stay available and ABI
                 compatible as long as the SONAME of libisoburn stays "1".
                 Currently there are no plans to ever change the SONAME.
                  
                 Odd numbers indicate that API upgrades are in progress.
                 I.e. new features might be already present or they might
                 be still missing. Newly introduced features may be changed
                 incompatibly or even be revoked before release of a pare
                 version.
                 So micro revisions {1,3,5,7,9} should never be used for
                 dynamic linking unless the proper library match can be
                 guaranteed by external circumstances.

/*
                           Message output evaluation

   xorriso is basically a dialog software which reacts on commands by
   side effects and by messages. The side effects manipulate the state of
   the ISO image model and of drives. This state can be inquired by commands
   which emit messages.

   There are several approaches how a program that uses xorriso via this API
   can receive and use the message output of xorriso.

   - The message sieve may be programmed to pick certain information snippets
     out of the visible message stream. This covers all messages on the
     result channel and those info channel messages which get not suppressed
     by command -report_about. All important info messages have severity NOTE
     or higher.
     Much of the message interpretation is supposed to happen by the sieve
     filter rules which describe the interesting message lines and the
     positions of the interesting message parts.
     The call Xorriso_sieve_big() installs a sieve that looks out for most
     model state messages which xorriso can emit. After a few commands
     the user will ask the sieve for certain text pieces that might have been
     caught.

   - The outlist stack may be used to catch messages in linked lists rather
     than putting them out on the message channels.
     All interpretation of the messages has to be done by the user of the
     xorriso API. Function Xorriso_parse_line() is intended to help with
     splitting up messages into words.
     The outlist stack is handy for catching the results of information
     commands with large uniform output or no well recognizable message
     prefix. Like -lsl, -getfacl, -status, -find ... -exec get_md5.
     One should push the stack before the command, pull it afterwards, examine
     the text list by Xorriso_lst_get_*(), and finally dispose the list.

   - The message watcher is a separate program thread which uses the outlist
     stack to catch the messages and to call user provided handler functions.
     These functions can use Xorriso_parse_line() too, if they submit the
     xorriso parameter as NULL. They may not use the struct XorrisO object
     in any way.
     Synchronization between watcher and emitters of commands can be achieved
     by Xorriso_peek_outlists().
     The main motivation for the message watcher is to inspect and display
     messages of long lasting xorriso commands while they are still executing.
     E.g. of -commit, -blank, -format.
     One would normally start it before such a command and stop it afterwards.
     But of course, the watcher can stay activated all the time and process
     all message output via its handler calls.

   The message sieve does not interfere with outlists and message watcher.
   The message watcher will only see messages which are not caught by outlists
   which were enabled after the watcher thread was started.

/* The programmable message sieve picks words out of the program messages
   of xorriso.
   The sieve is a collection of filter rules. Each one is defined by a call of
   Xorriso_sieve_add_filter(). The sieve watches the given output channels for
   messages which begin by the given text prefixes of the filters.
   Matching lines get split into words by Xorriso_parse_line() using
   the given separators. The words described by the filter's word index array
   get recorded by the filter and can be inquired by Xorriso_sieve_get_result()
   after one or more xorriso commands have been performed.
   The recorded results may be disposed by Xorriso_sieve_clear_results without
   giving up the sieve.
   The whole sieve may be disposed by Xorriso_sieve_dispose().
   Default at library start is an inactive sieve without any filter rules.

                      The prefix of the filter rule will then be adapted

   Before each call to a command function, there should happen:
   Xorriso_set_problem_status() with empty severity text.

   After each call to a command function, there should happen:
   Xorriso_eval_problem_status()
   One should follow its eventual advice to abort.

   Commands with a varying number of arguments get then passed like
   Xorriso_interpreter(). E.g.:
     int Xorriso_option_add(struct XorrisO *xorriso, int argc, char **argv,
                            int *idx, int flag);
   The command functions will begin to read the arguments at position *idx
   and will see the list end either at the next argv which contains the
   -list_delimiter text or at argv[argc-1].
   After the call, *idx will be the index of the first not yet interpreted
   argv.

   Do not set any flag bits which are not described by "@param flag".
   I.e. if flag is not mentioned, then submit 0.
   Yet undefined flag bits might get a meaning in future. Unset bits will
   then produce the traditional behavior, whereas set bits might bring
   surprises to inadverted callers.
