 *  Gestalt()
 *  
 *  Summary:
 *    Gestalt returns information about the operating environment.
 *  
 *  Discussion:
 *    The Gestalt function places the information requested by the
 *    selector parameter in the variable parameter response . Note that
 *    Gestalt returns the response from all selectors in an SInt32,
 *    which occupies 4 bytes. When not all 4 bytes are needed, the
 *    significant information appears in the low-order byte or bytes.
 *    Although the response parameter is declared as a variable
 *    parameter, you cannot use it to pass information to Gestalt or to
 *    a Gestalt selector function. Gestalt interprets the response
 *    parameter as an address at which it is to place the result
 *    returned by the selector function specified by the selector
 *    parameter. Gestalt ignores any information already at that
 *    address.
 *    
 *    The Apple-defined selector codes fall into two categories:
 *    environmental selectors, which supply specific environmental
 *    information you can use to control the behavior of your
 *    application, and informational selectors, which supply
 *    information you can't use to determine what hardware or software
 *    features are available. You can use one of the selector codes
 *    defined by Apple (listed in the "Constants" section beginning on
 *    page 1-14 ) or a selector code defined by a third-party
 *    product.
 *    
 *    The meaning of the value that Gestalt returns in the response
 *    parameter depends on the selector code with which it was called.
 *    For example, if you call Gestalt using the gestaltTimeMgrVersion
 *    selector, it returns a version code in the response parameter. In
 *    this case, a returned value of 3 indicates that the extended Time
 *    Manager is available.
 *    
 *    In most cases, the last few characters in the selector's symbolic
 *    name form a suffix that indicates what type of value you can
 *    expect Gestalt to place in the response parameter. For example,
 *    if the suffix in a Gestalt selector is Size , then Gestalt
 *    returns a size in the response parameter.
 *    
 *    Attr:  A range of 32 bits, the meanings of which are defined by a
 *    list of constants. Bit 0 is the least significant bit of the
 *    SInt32.
 *    Count: A number indicating how many of the indicated type of item
 *    exist.
 *    Size: A size, usually in bytes.
 *    Table: The base address of a table.
 *    Type: An index to a list of feature descriptions.
 *    Version: A version number, which can be either a constant with a
 *    defined meaning or an actual version number, usually stored as
 *    four hexadecimal digits in the low-order word of the return
 *    value. Implied decimal points may separate digits. The value
 *    $0701, for example, returned in response to the
 *    gestaltSystemVersion selector, represents system software version
 *    7.0.1.
 *    
 *    Selectors that have the suffix Attr deserve special attention.
 *    They cause Gestalt to return a bit field that your application
 *    must interpret to determine whether a desired feature is present.
 *    For example, the application-defined sample function
 *    MyGetSoundAttr , defined in Listing 1-2 on page 1-6 , returns a
 *    LongInt that contains the Sound Manager attributes field
 *    retrieved from Gestalt . To determine whether a particular
 *    feature is available, you need to look at the designated bit.

    --------------------------------------
    The version is stored in the high three bytes of the response value.  Let us number

        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:

        alpha       = 0x40
        beta        = 0x60

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

    However, the use of these selectors for pretty much anything is discouraged.
    If you are trying to determine if you can use a particular processor or
    operating system feature, it would be much better to check directly for that
    feature using one of the apis for doing so -- like, sysctl() or sysctlbyname().
    Those apis return information directly from the operating system and kernel.  By
    using those apis you may be able to avoid linking against Frameworks which you
    otherwise don't need, and may lessen the memory and code footprint of your
    applications.
    
    The gestaltNativeCPUfamily ('cpuf') selector can be used to determine the
    general family the native CPU is in.

    gestaltNativeCPUfamily uses the same results as gestaltNativeCPUtype, but
    will only return certain CPU values.
    
    IMPORTANT NOTE: gestaltNativeCPUFamily may no longer be updated for any new
                    processor families introduced after the 970.  If there are
                    processor specific features you need to be checking for in
                    your code, use one of the appropriate apis to get for those
                    exact features instead of assuming that all members of a given
                    cpu family exhibit the same behaviour.  The most appropriate api
                    to look at is sysctl() and sysctlbyname(), which return information
                    direct from the kernel about the system.

    MACHINE TYPE CONSTANTS NAMING CONVENTION

    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.

        Macintosh LC 630                gestaltMacLC630

    Because some PowerPC machines now support very large physical memory capacities, including
    some above the maximum value which can held in a 32 bit quantity, there is now a new selector,
    gestaltPhysicalRAMSizeInMegabytes, which returns the size of physical memory scaled
    in megabytes.  It is recommended that code transition to using this new selector if
    it wants to get a useful value for the amount of physical memory on the system.  Code can
    also use the sysctl() and sysctlbyname() BSD calls to get these kinds of values.
    
    For compatability with code which assumed that the value in returned by the
    gestaltPhysicalRAMSize selector would be a signed quantity of bytes, this selector will
    now return 2 gigabytes-1 ( INT_MAX ) if the system has 2 gigabytes of physical memory or more.

    Returns the system version as a 32 bit packed BCD ( binary coded decimal )
    version representation.  Bits 0 through 3 are the "bug fix" revision number.
    Bits 4 through 7 are the minor revision, and bits 8 through 31 are the bcd
    decimal digits of the major release version.
    
      Value:  0xMMMMMMRB = M.R.B            Example: 0x00001023 = 10.2.3
                ^^^^^^     major rev                   ^^^^^^   major rev   = 10
                      ^    minor rev                         ^  minor rev   =  2

    If the values of the minor or bug fix revision are larger than 9, then
    gestaltSystemVersion will substitute the value 9 for them.  For example,
    Mac OS X 10.3.15 will be returned as 0x1039, and Mac OS X 10.10.5 will
    return 0x1095.
    
    A better way to get version information with the deprecated Gestalt API
	would be to use the gestaltSystemVersionMajor, gestaltSystemVersionMinor,
    and gestaltSystemVersionBugFix selectors, which don't have arbitrary limits
    on the values returned. However, because Gestalt is deprecated, you should
	use NSProcessInfo's operatingSystemVersion property instead.
 
    If you want to know the product build version string, product name, or
    the user visible version string you should read in the system version
    information from the file /System/Library/CoreServices/SystemVersion.plist.
