Change History (most recent first):
<18> 7/30/91 JL Updated Copyright.
<17> 2/4/91 JL changed fullpath to fullPath; changed spelling capitalization.
<16> 1/28/91 JAL (MH)kARMmountVol etc. are now explicitly 32 bit constants (8 hex digits)
Checked in Database generated file.
<15> 1/7/91 JDR (dba) NewAliasMinimalFromFullpath had its case incorrect and is
now NewAliasMinimalFromFullPath to match the .h interface. Also
corrected the case for fullPathLength and fullPath.
<14> 11/29/90 PP (PP/ich) Fix a typo in Filter proc comment.
<13> 8/6/90 PP zoneName in MinimalFullpathAlias is Str32 and not Str31.
<12> 7/2/90 PP Add ResolveAliasFile.
<11> 6/20/90 ngk Removed CanonicalFileSpec and replaced it with FSSpec.
Added type def for AliasFilterProcPtr. Changed
yourDataPtr type to UNIV Ptr.
<10> 6/15/90 PP Remove SelectAlias.
<9> 4/10/90 PP Add kARMnoUI bit for rules mask.
<8> 4/7/90 ngk Change fromFile back to an CanonicalFileSpecPtr, since it can be
NIL.
<7> 4/5/90 PP Add kARMsearchRelFirst to MatchAlias rulesMask. Rename
"callbackPtr" to "yourDataPtr".
<6> 3/20/90 PP Add interfaces for minimal alias support. userType in alias
record is OSType and not ResType.
<3> 1/26/90 ngk Changed CanonicalFileSpecPtr to CanonicalFileSpec in NewAlias
<2> 1/7/90 ngk Fix comments
<1> 1/7/90 ngk Renamed from Alias.p to Aliases.p
<1.9> 12/15/89 prp Fix parameter variable names.
<1.8> 10/2/89 prp Added 'GetAliasInfo' routine.
<1.7> 9/18/89 ngk removed old API definitions.
<1.6> 9/18/89 prp SelectAlias, MatchAlias and UpdateAlias has API changes with
additional parameters.
<1.5> 9/6/89 prp Added DisposeAlias back until DPMgr is in sync.
<1.4> 9/6/89 prp Changes from CodeReview.
<1.3> 8/7/89 prp Added SelectAlias routine as an external interface.
<1.2> 6/12/89 prp Took out emphasize relative path rules bit.
<1.1> 6/8/89 prp Alias Manager Trap # changed from $A825 to $A823
<1.0> 5/30/89 ngk Submitted for first time
