Trinity in Trouble

Note

Based on Free Pascal branch "fixes 3.0"

Feel free to add delete or change status.

Our trinity consist of Amiga, AROS and MorphOS.

Unfortunately, there are (still) some incompatibilities and/or some lack of consistency here and there. The idea is to have a list here that mentions them all. Layout may change, i simply had to start somewhere.

NOTE: I thought there is no use to mention the Tag, Tags, Taglist, etc. inconsistency and additional incompatibilities that this causes. We are all aware of those and will hopefully get some unity in the future

List of issues

• function: DoMethod()

Amiga version seems missing completely.

Implemented versions for AROS and MorphOS don't follow autodocs 100% and are inconsistent.

• function: ASLRequestTags()

AROS implementation seems missing.

Amiga implements it in utility unit systemvartags (see also unit: systemvartags)

MorphOS implements it in unit ASL

• structure: Hook

AROS version, entries are not IPTR rather APTR.

• function: GetAttr()

Amiga + MorphOS uses a var for ReturnValue while AROS uses a pointer. Autodocs states it to be a pointer.

• function: SetAttrs()

Amiga + MorphOS implementations seems missing

• unit: Workbench

MorphOS version seems missing

• unit: systemvartags

This utility unit is Amiga specific and implements most if not all vartags versions of library-calls rendering it incompatible with AROS and MorphOS

• function: AllocMem() (high priority)

MorphOS implemented it as ExecAllocMem

Amiga + AROS version have this function declared as AllocMem(), which is ambiguous with Free Pascal's AllocMem function.

• function: Info()

AutoDocs: BOOL = Info( BPTR, struct InfoData * )

Amiga declaration: FUNCTION Info(lock : LONGINT location 'd1'; parameterBlock : pInfoData location 'd2') : LongBool; syscall _DOSBase 114;

AROS declaration: function Info(Lock: BPTR; ParameterBlock: PInfoData): LongInt; syscall AOS_DOSBase 19;

MorphOS declaration: function Info(lock : LongInt location 'd1'; parameterBlock: PInfoData location 'd2'): LongInt; SysCall MOS_DOSBase 114;
