This includes media like DVD+RW, which do not support multi-session 00015 management on media level and even plain disk files or block devices. 00016 00017 The price for that is thorough specialization on data files in ISO-9660 00018 filesystem images. So libisoburn is not suitable for audio (CD-DA) or any 00019 other CD layout which does not entirely consist of ISO-9660 sessions. 00020 00021 Note that there is a higher level of API: xorriso.h. One should not mix it 00022 with the API calls of libisoburn.h, libisofs.h, and libburn.h. 00023 00024 00025 Connector functions 00026 00027 libisofs and libburn do not depend on each other but share some interfaces 00028 by which they can cooperate. 00029 libisoburn establishes the connection between both modules by creating the 00030 necessary interface objects and attaching them to the right places. 00031 00032 00033 Wrapper functions 00034 00035 The priciple of this frontend is that you may use any call of libisofs or 00036 libburn unless it has a isoburn_*() wrapper listed in the following function 00037 documentation. 00038 00039 E.g. call isoburn_initialize() rather than iso_init(); burn_initialize(); 00040 and call isoburn_drive_scan_and_grab() rather than burn_drive_scan_and_grab(). 00041 But you may call burn_disc_get_profile() directly if you want to display 00042 the media type. 00043 00044 The wrappers will transparently provide the necessary emulations which 00045 are appropriate for particular target drives and media states. 00046 To learn about them you have to read both API descriptions: the one of 00047 the wrapper and the one of the underlying libburn or libisofs call. 00048 00049 Macros BURN_* and functions burn_*() are documented in <libburn/libburn.h> 00050 Macros ISO_* and functions iso_*() are documented in <libisofs/libisofs.h> 00051 00052 00053 Usage model 00054 00055 There may be an input drive and an output drive. Either of them may be missing 00056 with the consequence that no reading resp. writing is possible. 00057 Both drive roles can be fulfilled by the same drive. 00058 00059 Input can be a random access readable libburn drive: 00060 optical media, regular files, block devices. 00061 Output can be any writeable libburn drive: 00062 writeable optical media in burner, writeable file objects (no directories). 00063 00064 libburn demands rw-permissions to drive device file resp. file object. 00065 00066 If the input drive provides a suitable ISO RockRidge image, then its tree 00067 may be loaded into memory and can then be manipulated by libisofs API calls. 00068 The loading is done by isoburn_read_image() under control of 00069 struct isoburn_read_opts which the application obtains from libisoburn 00070 and manipulates by the family of isoburn_ropt_set_*() functions. 00071 00072 Writing of result images is controlled by libisofs related parameters 00073 in a struct isoburn_imgen_opts which the application obtains from libisoburn 00074 and manipulates by the family of isoburn_igopt_set_*() functions. 00075 00076 All multi-session aspects are handled by libisoburn according to these 00077 settings. The application does not have to analyze media state and write 00078 job parameters. It rather states its desires which libisoburn tries to 00079 fulfill, or else will refuse to start the write run. 00080 00081 00082 Setup for Growing, Modifying or Blind Growing 00083 00084 The connector function family offers alternative API calls for performing 00085 the setup for several alternative image generation strategies. 00086 00087 Growing: 00088 If input and output drive are the same, then isoburn_prepare_disc() is to 00089 be used. It will lead to an add-on session on appendable or overwriteable 00090 media with existing ISO image. With blank media it will produce a first 00091 session. 00092 00093 Modifying: 00094 If the output drive is not the input drive, and if it bears blank media 00095 or overwriteable without a valid ISO image, then one may produce a consolidated 00096 image with old and new data. This will copy file data from an eventual input 00097 drive with valid image, add any newly introduced data from the local 00098 filesystem, and produce a first session on output media. 00099 To prepare for such an image generation run, use isoburn_prepare_new_image(). 00100 00101 Blind Growing: 00102 This method reads the old image from one drive and writes the add-on session 00103 to a different drive. That output drive is nevertheless supposed to 00104 finally lead to the same medium from where the session was loaded. Usually it 00105 will be stdio:/dev/fd/1 (i.e. stdout) being piped into some burn program 00106 like with this classic gesture: 00107 mkisofs -M $dev -C $msc1,$nwa | cdrecord -waiti dev=$dev 00108 Blind growing is prepared by the call isoburn_prepare_blind_grow(). 00109 The input drive should be released immediately after this call in order 00110 to allow the consumer of the output stream to access that drive for writing. 00111 00112 After either of these setups, some peripheral libburn drive parameter settings 00113 like burn_write_opts_set_simulate(), burn_write_opts_set_multi(), 00114 burn_drive_set_speed(), burn_write_opts_set_underrun_proof() should be made. 00115 Do not set the write mode. It will be chosen by libisoburn so it matches job 00116 and media state. 00117 00118 Writing the image 00119 00120 Then one may start image generation and write threads by isoburn_disc_write(). 00121 Progress may be watched at the output drive by burn_drive_get_status() and 00122 isoburn_get_fifo_status(). 00123 00124 At some time, the output drive will be BURN_DRIVE_IDLE indicating that 00125 writing has ended. 00126 One should inquire isoburn_drive_wrote_well() to learn about overall success. 00127 00128 Finally one must call isoburn_activate_session() which will complete any 00129 eventual multi-session emulation. 00130 00131 00132 Application Constraints 00133 00134 Applications shall include libisofs/libisofs.h , libburn/libburn.h and this 00135 file itself: libisoburn/libisoburn.h . 00136 They shall link with -lisofs -lburn -lisoburn or with the .o files emerging 00137 from building those libraries from their sources. 00138 00139 Applications must use 64 bit off_t. 00140 E.g. on 32-bit GNU/Linux by defining 00141 #define _LARGEFILE_SOURCE 00142 #define _FILE_OFFSET_BITS 64 00143 The minimum requirement is to interface with the library by 64 bit signed 00144 integers where libisofs.h or libisoburn.h prescribe off_t. 00145 Failure to do so may result in surprising malfunction or memory faults. 00146 00147 Application files which include libisofs/libisofs.h or libisoburn/libisoburn.h 00148 must provide definitions for uint32_t and uint8_t. 00149 This can be achieved either: 00150 - by using autotools which will define HAVE_STDINT_H or HAVE_INTTYPES_H 00151 according to its ./configure tests, 00152 - or by defining the macros HAVE_STDINT_H resp. HAVE_INTTYPES_H according 00153 to the local situation, 00154 - or by appropriately defining uint32_t and uint8_t by other means, 00155 e.g. by including inttypes.h before including libisofs.h and libisoburn.h 00156 00157 */ 00158 #ifdef HAVE_STDINT_H 00159 #include <stdint.h> 00160 #else 00161 #ifdef HAVE_INTTYPES_H 00162 #include <inttypes.h> 00163 #endif 00164 #endif 00165 00166 00167 /* Important: If you add a public API function then add its name to file 00168 libisoburn/libisoburn.ver 00169 */ 00170 00171 00172 /* API functions */ 00173 00174 00175 /** Initialize libisoburn, libisofs and libburn. 00176 Wrapper for : iso_init() and burn_initialize() 00177 @since 0.1.0 00178 @param msg A character array for eventual messages (e.g. with errors) 00179 @param flag Bitfield for control purposes (unused yet, submit 0) 00180 @return 1 indicates success, 0 is failure 00181 */ 00182 int isoburn_initialize(char msg[1024], int flag); 00183 00184 00185 /** Check whether all features of header file libisoburn.h from the given 00186 major.minor.micro revision triple can be delivered by the library version 00187 which is performing this call. 00188 An application of libisoburn can easily memorize the version of the 00189 libisoburn.h header in its own code.

I.e. be master of your 00337 build system and have #if checks in the source code 00338 of your application, nevertheless. 00339 00340 At runtime (via *_is_compatible()): 00341 00342 Vreixo Formoso advises to compare the application's 00343 requirements of library revisions with the runtime 00344 library. This is to allow runtime libraries which are 00345 young enough for the application but too old for 00346 the lib*.h files seen at compile time. 00347 00348 Thomas Schmitt advises to compare the header 00349 revisions defined here with the runtime library. 00350 This is to enforce a strictly monotonous chain 00351 of revisions from app to header to library, 00352 at the cost of excluding some older libraries. 00353 00354 These two advises are mutually exclusive. 00355 00356 ----------------------------------------------------- 00357 00358 For an implementation of the Thomas Schmitt approach, 00359 see libisoburn/burn_wrap.c : isoburn_initialize() 00360 This connects libisoburn as "application" with libisofs 00361 as "library". 00362 00363 The compatible part of Vreixo Formoso's approach is implemented 00364 in configure.ac LIBBURN_REQUIRED, LIBISOFS_REQUIRED. 00365 In isoburn_initialize() it would rather test by 00366 iso_lib_is_compatible(isoburn_libisofs_req_major,... 00367 than by 00368 iso_lib_is_compatible(iso_lib_header_version_major,... 00369 and would leave out the ugly compile time traps. 00370 00371 */ 00372 00373 00374 /** Announce to the library an application provided method for immediate 00375 delivery of messages.
