Gestalt Selectors List

General Info

The following sections provide general information needed or useful in relation to the Gestalt Manager.

System Managers

Listed below is a table with the different software components of the System Software with their related selectors. The selectors listed with this table are included in the (known) 'Apple System Software' and 'Apple Additional Software' chapters.
It provides a cross-reference to selectors and a starting point into other documentation (Inside Macintosh).
With System Software versions before 6.0.4 (and Gestalt) you may need to use TrapAvailable to determine the presence of certain system parts.

The Gestalt Mgr with System 7.1.2 is suspected of doing several things wrong. This should be fixed with System 7.5 or later.
Also note that with the minimal software installation, i.e. the Disk Tools disk, the system software may lie about the managers present.

The Communications Toolbox for System 6 doesn't install any of the CTB related selectors.

A general Gestalt problem is that NewGestalt calls StripAddress on the procptr passed to it, not on a local copy, so the stripping becomes permanent. This is fixed by System 7.5.1 and later.

Inside Macintosh Operating System Utilities says (on page 1-37) the A0 and D0 registers are used to pass/return data to/from the selector function, MySelectorFunction. This is incorrect since the function is Pascal stack based. (Nobu Toge, Steve Ko)


This section contains a short overview about the history of the Gestalt Manager and its predecessors.


     PROCEDURE Environs (VAR rom,machine: INTEGER);

With the introduction of the Macintosh the system routine 'Environs' was introduced. It allowed to obtain two pieces of information: the ROM version and a value to indicate the machinetype. This "ROM oriented" way soon appeared to be insufficient when the range of Macintosh hardware and software became more diverse.


     FUNCTION SysEnvirons (versionRequested: INTEGER;
                           VAR theWorld: SysEnvRec): OSErr;

With System 4.1 a new system routine was introduced which allowed the programmer to obtain more information about the current configuration. Upon completion SysEnvirons filled the SysEnvRec with the information. This was however an "all-or-nothing" situation, it was not possible to obtain just one piece of information.
To allow for larger system environment records with more information one needed to specify the version number of the system environment record. The last version, introduced with System 6, was version 2 which had nine fields.


     FUNCTION Gestalt (code: LONGINT; VAR feature: LONGINT): OSErr;

You may wonder how one can be so stupid to list the Gestalt routine wrong...
However, this is how the Gestalt routine was presented to developers in the Preliminairy Developer Note regarding System 7 in 1989. It was originally written in 1988.
There was no selector of type OSType as we known it today. Instead a list of numerical constants was used, like:

     zVersion    = $1;   { Gestalt Version }
     zMachType   = $100; { machine type }
     zSystemVers = $101; { system file version }

and nine others.
But the principle used with todays Gestalt routine was there: request one specific piece of information and you'll get it. Nothing more and nothing less. Back then it wasn't the Gestalt Manager since there was only one routine. Both the NewGestalt and the ReplaceGestalt did not exist.
In June 1992 (released in February 1993?) four new functions were added to the Gestalt Manager: NewGestaltValue, ReplaceGestaltValue, DeleteGestaltValue and SetGestaltValue.
The first name/initials of the programmers are returned by two special selectors, namely (OSType) 7 and (OSType) 13. Their names can not be disclosed.
