API documentation for libmpg123, libout123, and libsyn123

Note: This API doc is automatically generated from the current development version that you can get via Subversion or as a daily snapshot from http://mpg123.org/snapshot. There may be differences (additions) compared to the latest stable release. See NEWS.libmpg123, NEWS.libout123, NEWS.libsyn123, and the overall NEWS file on libmpg123 versions and important changes between them.
Let me emphasize that the policy for the lib*123 family is to always stay backwards compatible -- only additions are planned (and it's not yet planned to change the plans;-).

55 /* Simplified large file handling.
56  I used to have a check here that prevents building for a library with conflicting large file setup
57  (application that uses 32 bit offsets with library that uses 64 bits).
58  While that was perfectly fine in an environment where there is one incarnation of the library,
59  it hurt GNU/Linux and Solaris systems with multilib where the distribution fails to provide the
60  correct header matching the 32 bit library (where large files need explicit support) or
61  the 64 bit library (where there is no distinction).
62 
63  New approach: When the app defines _FILE_OFFSET_BITS, it wants non-default large file support,
64  and thus functions with added suffix (mpg123_open_64).
65  Any mismatch will be caught at link time because of the _FILE_OFFSET_BITS setting used when
66  building libmpg123. Plus, there's dual mode large file support in mpg123 since 1.12 now.
67  Link failure is not the expected outcome of any half-sane usage anymore.
68 
69  More complication: What about client code defining _LARGEFILE64_SOURCE? It might want direct access to the _64 functions, along with the ones without suffix. Well, that's possible now via defining MPG123_NO_LARGENAME and MPG123_LARGESUFFIX, respectively, for disabling or enforcing the suffix names.
70 */
71 
72 /*
73  Now, the renaming of large file aware functions.
74  By default, it appends underscore _FILE_OFFSET_BITS (so, mpg123_seek_64 for mpg123_seek), if _FILE_OFFSET_BITS is defined. You can force a different suffix via MPG123_LARGESUFFIX (that must include the underscore), or you can just disable the whole mess by defining MPG123_NO_LARGENAME.
