Short: Dynamic buffers (IFF streamable) + support funcs
Author: RhoSigma, Roland Heyder <http://rhosigma-cw.net/>
Uploader: Roland Heyder <rhosigma rhosigma-cw net>
Type: util/libs
Version: 4.800 (12.05.15)
Architecture: m68k-amigaos >= 2.0.0

The ExtraLib package is FREEWARE.
=> some features of this library
- support functions to compute checksums in standard amiga filesystems
- complex dynamic buffer system for easy data handling in memory
- buffers usable as source/target for IFF-Streams via InitIFFasDBS()
- no buffer cleanup required, the library keeps track of resources
- a somewhat more fancy »DisplayAlert()«-replacement function
- some functions for formatted output and number <-> string conversion
- no string cleanup required, the library keeps track of resources
=> as far as I could test it (WinUAE 3.0.0), the library does also work
with AmigaOS 4.x (Classic Versions)
=> sorry, the developer documentation and include files are currently
available in german only
=> if you wrote software using any functions of the extra.library, then
feel free to distribute a standalone copy of the library enclosed with
your package, but please mention the ExtraLib.lha archive as its source
and Aminet util/libs as the place to go for download

Das ExtraLib Packet ist FREIWARE.
=> einige Eckpunkte dieser Library
- Hilfsfunktionen zur Checksummenbildung in Standard-Amiga-Filesystemen
- ein dynamisches Puffer-System für einfache Datenhandhabung im Speicher
- Puffer können als IFF Ein-/Ausgabe genutzt werden über InitIFFasDBS()
- kein Aufräumen erforderlich, die Library erledigt das automatisch
- eine etwas schönere Funktion als »DisplayAlert()«-Ersatz
- Funktionen zur formatierten Ausgabe und Zahl <-> String Umwandlung
- kein Aufräumen erforderlich, die Library erledigt das automatisch
=> soweit ich das testen konnte (WinUAE 3.0.0), arbeitet die Library auch
mit AmigaOS 4.x (Klassik Versionen)
=> wenn du Programme geschrieben hast, die irgendwelche Funktionen aus der
extra.library benutzen, dann darfst du auch gerne eine Einzelkopie der
Bibliothek deinem Programmpacket beilegen, aber bitte weise darauf hin,
daß die Quelle das ExtraLib.lha Archiv ist und dieses auf dem Aminet
unter util/libs zum herunterladen bereit steht

===========================================================================
Early History:
¯¯¯¯¯¯¯¯¯¯¯¯¯¯
v0.000 (18.11.98)
- history for old versions before v4.000 is removed for cleanup, also
any further support for those old versions has been dropped now
- compatiblity for old software depends on the software itself, if
it was following given old rules, then everything should work fine
- new software should ALWAYS OpenLibrary() with at least version 4
and also use the most recent developer files
- if you have old source code which is using the extra.library, then
it's maybe a good idea to recompile it now for v4.000+ usage
- before recompile the old v2_XXX function names must be renamed to
its new names, simply remove the 'v2_' prefix from function names
and instead append 'Type' to the names, e.g. v2_OpenBuf() is now
named OpenBufType()
History (cleaned for v4.000+):
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
v4.000 (26.05.03)
- is now the lowest supported version, you will find a EXTRA_MINIMUM
symbol defined in the include files to reflect this
v4.172 (21.06.03)
- fixed a bug in »StringToLong()«, plus (+) is now also accepted for
signed value strings
- had some random crashes caused by »UnGetMem()« with any other
argument given than »NULL«, intercepted and fixed now
- little change within »ShowMsg()«, if a button is pressed, then it
now waits until it is released again to avoid multiple screen
flipping, which happens in case a retry loop is active and the
function is reentered before the button is released
v4.516 (30.05.04)
- changed »PrintIoError()« and »ShowMsg()«, beside left/right mouse
buttons, you can also use the keys LALT/LAMIGA and RALT/RAMIGA now
to make a selection
v4.630 (26.11.05)
- fixed some minor bugs in number <-> string conversion routines
- improved »VSPrintF()« string length calculation to make it safer
against random buffer overflows (which mostly did cause a crash)
v4.633 (04.06.06)
- small improvements done on internal memory mangement, which I've
learned during the work on my MemOptimizer project
(see util/boot/MemOptimizer.lha)
- an uninitialized list header was used in string conversion routines,
minor bug, because only used in very rare cases, but fixed now
v4.649 (08.09.06)
- bugfix in »Replace()« for OldSize/NewSize Checks, in certain rare
cases a buffer overflow could happen while writing the new data
- bugfix in »FindString()« for Size Check, did only check WORD-Size,
hence sizes with bit 15 set were interpreted as negative, which
could cause an early abort or wrong search result
- better ModeID Check for »ShowMsg()« to find out if an RTG or AGA
should be used depending on the current front screen
- optimized »CmpMem()«, »CopyMemI()« and »FillMem()«, saved some
cycles within the internal loops, hence time per loop is less now,
which should speedup at least large size calls a bit
v4.800 (12.05.15)
- cleaned up and final release
- fixed two Mungwall-Hits, which were harmless on classic AmigaOS
versions upto 3.9 but caused DSI errors with AmigaOS 4.x
- unfortunately I've never received any comments, bugreports or
suggestions during all the years since 1998, so I must assume I'm
the only one who's really using this library, by this means...
