; Change History (most recent first):
;
; <15> 10/7/92 gs Add btTooManyNodesErr (-430) for OCE folks to get around DIVU
; "bug".
; <14> 8/21/91 JSM Clean up header.
; <13> 1/30/91 gbm sab, #38: Change the already including this file variable to
; all uppercase (for security reasons)
; <12> 1/4/91 KST With dnf: Took out the definition of 'kdDTString' and changed
; the type number to 'kdReserved'.
; <11> 8/3/90 KST Adding a new field ioBTWriteFlag in BTioParam structure.
; <10> 7/17/90 KST btRsrvedErr is no longer used.
; <9> 7/17/90 KST Adding 2 error codes.
; <8> 7/6/90 KST Changing maxKeyLen from 127 to 129 per AppleMail request.
; <6> 4/9/90 KST Making necessary changes to support user specified key
; comparison procedure.
; <5> 4/4/90 KST Adding new error codes.
; <4> 3/13/90 KST Adding a new error code -- "btVersionErr".
; <3> 2/23/90 KST Adding a new error code -- btNoKDErr.
; <2> 2/22/90 KST Moved B*tree error codes from SysErr.a into this file. Added a
; new field in BTioParam.
; <1> 2/21/90 HJR Moved from Interfaces:AIncludes to Internal:Asm.
; <4> 2/6/90 KST Adding a new call, btUpdateKD.
; <3> 1/22/90 KST Added new access control calls and rewrote btree macros.
; <2.1> 10/16/89 KST Added new _BTCleanUp trap and selector.
; <2.0> 10/3/89 KST Moved B*Tree assembly routine macros from Hfs70Equ.a to
; BTreeEqu.a. Changed ioKBufSize to ioKReqCount.
; <1.9> 9/18/89 KST Added a new type kdDTString to replace default for DTDB.
; <1.8> 8/16/89 KST BTHints are not exported to the public.
; <1.7> 8/7/89 KST Moved error codes to sysErr.a and Moved btQType to sysEqu.a
; <1.6> 7/6/89 KST Added BTFlush call.
; <1.5> 6/15/89 KST maxKeylen is used by DTMgr, so it can't be in BTreePrivate.a
; <1.4> 6/15/89 KST Separate private stuff from BTreeEqu.a
; <1.3> 6/14/89 KST Made changes for the new implementation of BTreeMgr.
; <1.2> 3/21/89 KST Changed BTError code, added support for Mac Plus.
; <1.1> 3/8/89 KST Added IMPORT for cmdAddr and fsqAddr.
; <1.0> 3/8/89 KST Adding to EASE for the first time.
