Inside Macintosh: Sound

Version Records

The functions SndSoundManagerVersion and MACEVersion return version information using a version record. The NumVersion data type defines a version record.

    (majorRev:              SignedByte;         {major revision level in BCD}

    minorAndBugRev:         SignedByte;         {minor revision level}

    stage:                  SignedByte;         {development stage}

A version record has the same structure as the first four fields of a version resource (a resource of type 'vers' ). See the chapter "Finder Interface" in Inside Macintosh: Macintosh Toolbox Essentials for complete information about version resources.

majorRev: The major revision level. This field is a signed byte in binary-coded decimal format.
minorAndBugRev: The minor revision level. This field is a signed byte in binary-coded decimal format.
stage: The development stage. You should use the following constants to specify a development stage:



 
                    CONST

                        developStage            = $20;      {prealpha release}

                        alphaStage              = $40;      {alpha release}

                        betaStage               = $60;      {beta release}

                        finalStage              = $80;      {final release}

nonRelRev: The revision level of a prereleased version.
version: A long integer that contains all four version fields.
