|
|
*
|
|
* It is about whether to use at compile time and at runtime the version

|
* numbers provided here. Thomas Schmitt advises to use them. Vreixo Formoso
|
|
* advises to use other means.
|
|
*
|
|
* At compile time:
|
|
*
|
|
* Vreixo Formoso advises to leave proper version matching to properly
|
|
* programmed checks in the the application's build system, which will
|
|
* eventually refuse compilation.
|
|
*
|
|
* Thomas Schmitt advises to use the macros defined here for comparison with
|
|
* the application's requirements of library revisions and to eventually
|
|
* break compilation.
|
|
*
|
|
* Both advises are combinable. I.e. be master of your build system and have
|
|
* #if checks in the source code of your application, nevertheless.
|
|
*
|
|
* At runtime (via iso_lib_is_compatible()):
|
|
*
|
|
* Vreixo Formoso advises to compare the application's requirements of
|
|
* library revisions with the runtime library. This is to allow runtime
|
|
* libraries which are young enough for the application but too old for
|
|
* the lib*.h files seen at compile time.
|
|
*
|
|
* Thomas Schmitt advises to compare the header revisions defined here with
|
|
* the runtime library. This is to enforce a strictly monotonous chain of
|
|
* revisions from app to header to library, at the cost of excluding some older
|
|
* libraries.
|
|
*
|

|

|
|
* image generation. It may be the one announced to libisofs or an intermediate
|
|
* one. Nevertheless, the image will be readable only at the announced address.

|
|
* libisoburn emulates multisession appendability on overwriteable media
|
|
* and disk files by performing this use case.
|
|
*
|
|
* - Together with iso_write_opts_set_appendable(opts, 0) the buffer allows
|
|
* to write the first session on overwriteable media to start addresses
|
|
* other than 0.
|
|
* libisoburn in most cases writes the first session on overwriteable media
|

|
|
* subsequent overwriting by the descriptor buffer of later sessions.

|
