Gestalt selector for determining Appearance Manager version
If this selector does not exist, but gestaltAppearanceAttr
does, it indicates that the 1.0 version is installed. This
gestalt returns a BCD number representing the version of the
Appearance Manager that is currently running, e.g. 0x0101 for version 1.0.1.

FORMAT OF gestaltATalkVersion RESPONSE

The version is stored in the high three bytes of the response value. Let us number the bytes in the response value from 0 to 3, where 0 is the least-significant byte. 

 Byte#:     3 2 1 0
 Value:  0xMMNNRR00

Byte 3 (MM) contains the major revision number, byte 2 (NN) contains the minor revision number, and byte 1 (RR) contains a constant that represents the release stage. Byte 0 always contains 0x00. The constants for the release stages are: 

 development = 0x20
 alpha       = 0x40
 beta        = 0x60
 final       = 0x80
 release     = 0x80

For example, if you call Gestalt with the 'atkv' selector when AppleTalk version 57 is loaded, you receive the long integer response value 0x39008000.

The gestaltNativeCPUtype ('cput') selector can be used to determine the native CPU type for all Macs running System 7.5 or later.

The 'cput' selector is not available when running System 7.0 (or earlier) on most 68K machines. If 'cput' is not available, then the 'proc' selector should be used to determine the processor type.

An application should always try the 'cput' selector first. This is because, on PowerPC machines, the 'proc' selector will reflect the CPU type of the emulator's "virtual processor" rather than the native CPU type.

The values specified below are accurate. Prior versions of the Gestalt interface file contained values that were off by one.

The Quadra 840AV and the Quadra 660AV contain a bug in the ROM code that causes the 'cput' selector to respond with the value 5. This behavior occurs only when running System 7.1. System 7.5 fixes the bug by replacing the faulty 'cput' selector function with the correct one.

The gestaltNativeCPUfamily ('cpuf') selector can be used to determine the general family the native CPU is in. This can be helpful for determing how blitters and things should be written. In general, it is smarter to use this selector (when available) than gestaltNativeCPUtype since newer processors in the same family can be handled without revising your code.

gestaltNativeCPUfamily uses the same results as gestaltNativeCPUtype, but will only return certain CPU values.

MACHINE TYPE CONSTANTS NAMING CONVENTION 

All future machine type constant names take the following form:

    gestalt<lineName><modelNumber>

Line Names 

The following table contains the lines currently produced by Apple and

the lineName substrings associated with them: 

     Line                        lineName
     -------------------------   ------------
     Macintosh LC                "MacLC"
     Macintosh Performa          "Performa"
     Macintosh PowerBook         "PowerBook"
     Macintosh PowerBook Duo     "PowerBookDuo"
     Power Macintosh             "PowerMac"
     Apple Workgroup Server      "AWS"

 The following table contains lineNames for some discontinued lines:

     Line                        lineName
     -------------------------   ------------
     Macintosh Quadra            "MacQuadra" (preferred)
                                 "Quadra" (also used, but not preferred)
     Macintosh Centris           "MacCentris"

Model Numbers 

The modelNumber is a string representing the specific model of the

machine within its particular line. For example, for the Power Macintosh 8100/80, the modelNumber is "8100". 

 Some Performa & LC model numbers contain variations in the rightmost 1

or 2 digits to indicate different RAM and Hard Disk configurations. A single machine type is assigned for all variations of a specific model number. In this case, the modelNumber string consists of the constant leftmost part of the model number with 0s for the variant digits. For example, the Performa 6115 and Performa 6116 are both return the same machine type constant: gestaltPerforma6100.

OLD NAMING CONVENTIONS

The "Underscore Speed" suffix 

In the past, Apple differentiated between machines that had the same

model number but different speeds. For example, the Power Macintosh 8100/80 and Power Macintosh 8100/100 return different machine type constants. This is why some existing machine type constant names take the form: 

     gestalt<lineName><modelNumber>_<speed>

 e.g.

     gestaltPowerMac8100_110
     gestaltPowerMac7100_80
     gestaltPowerMac7100_66

 It is no longer necessary to use the "underscore speed" suffix. Starting

with the Power Surge machines (Power Macintosh 7200, 7500, 8500 and 9500), speed is no longer used to differentiate between machine types. This is why a Power Macintosh 7200/75 and a Power Macintosh 7200/90 return the same machine type constant: gestaltPowerMac7200.

The "Screen Type" suffix 

All PowerBook models prior to the PowerBook 190, and all PowerBook Duo

models before the PowerBook Duo 2300 take the form: 

     gestalt<lineName><modelNumber><screenType>

 Where <screenType> is "c" or the empty string.

 e.g.

     gestaltPowerBook100
     gestaltPowerBookDuo280
     gestaltPowerBookDuo280c
     gestaltPowerBook180
     gestaltPowerBook180c

 Starting with the PowerBook 190 series and the PowerBook Duo 2300

series, machine types are no longer differentiated based on screen type. This is why a PowerBook 5300cs/100 and a PowerBook 5300c/100 both return the same machine type constant: gestaltPowerBook5300.

The name gestaltMixedModeVersion for the 'mixd' selector is semantically incorrect. The same selector has been renamed gestaltMixedModeAttr to properly reflect the Inside Mac: PowerPC System Software documentation. The gestaltMixedModeVersion symbol has been preserved only for backwards compatibility.

Developers are forewarned that gestaltMixedModeVersion has a limited lifespan and will be removed in a future release of the Interfaces.

For the first version of Mixed Mode, both meanings of the 'mixd' selector are functionally identical. They both return 0x00000001. In subsequent versions of Mixed Mode, however, the 'mixd' selector will not respond with an increasing version number, but rather, with 32 attribute bits with various meanings.

◆ Gestalt()

OSErr Gestalt ( OSType  selector,
long *  response 
)

Get information about the operating environment. 

OSType selector ;Gestalt selector code
long *response ;4-byte return result
returns Error Code ; 0=no error
Gestalt provides your application with information about specific hardware
and software features.
selector is either a predefined code or an application-defined code
requesting information on a specific hardware or software feature
(see Using the Gestalt Manager for a list of selector codes).
response is the return value that provides the requested
information. Gestalt must already recognize the selector parameter
in order to return a response.
Returns
an operating system Error Code .
It will be one of:
noErr(0) No error
gestaltUnknown (-5550) Could not obtain the response
gestaltUndefSelectorErr (-5551) Undefined selector
Note
Gestalt returns the results from all function selectors in a 4-byte long
integer. Where not all 4 bytes are needed, the result is expressed in the
low-order bytes.
Being passed a predefined selector code doesn't cause Gestalt to move or
purge memory and therefore may be called even at interrupt time.
However, application-defined selector codes may move or purge memory
and applications can alter Gestalt's predefined selector functions. Given
all of that, you should always assume that Gestalt might always move or
purge memory.
THINK C 5.0 or later, THINK Pascal 4.0 or later and MPW 3.2 or later
contain glue that make it possible to call Gestalt under System versions
which do not support Gestalt (earlier than System 6.0.4). When possible,
the glue will call other traps in order to obtain the information requested.
If the selector is not available, a gestaltUndefSelectorErr will be returned.
Note that if you are programming in assembly language, this glue is not
provided. The following selectors are made available by this glue:
gestaltVersion
gestaltMachineType
gestaltSystemVersion
gestaltProcessorType
gestaltFPUType
gestaltQuickdrawVersion
gestaltKeyboardType
gestaltAppleTalkVersion
gestaltMMUType
