; 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 Ôalready including this fileÕ 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.
