|
; Change History (most recent first):
|
|
;
|
|
; <SM2> 8/3/93 BH Added VCB flags for use with manually ejectable volumes:
|
|
; vcbManEjBit and vcbFlushCritBit.
|
|
; <15> 8/14/91 JL changed lower case equ to EQU to match database output.
|
|
; <14> 1/30/91 gbm sab, #38: Change the Ôalready including this fileÕ variable to
|
|
; all uppercase (for security reasons)
|
|
; <13> 1/25/91 stb JDR: add constants missing in this file
|
|
; <12> 12/5/90 dnf Change <11> was with dba.
|
|
; <11> 12/5/90 dnf Add bHasBlankAccessPrivileges bit and volume meta buffer equates
|
|
; for GetVolParms.
|
|
; <10> 11/27/90 PWD Added equates for VolumeMount and its close relatives.
|
|
; <9> 11/27/90 PWD Add VolumeMount equates
|
|
; <8> 6/14/90 PK adding vcbAtBB, for sparing
|
|
; <5> 3/16/90 dnf Add FSSpec
|
|
; <4> 3/11/90 ngk Added more GetVolParms bits
|
|
; <2> 2/4/90 DNF Added fsSBNegate
|
|
; <1.3> 12/8/89 dnf Rolled in bit position equates for ioSpecBits in CatSearch
|
|
; <1.2> 8/2/89 CCH Added HVolumeParam record variant.
|
|
; <1.1> 2/6/89 CCH Added HParamBlock record.
|
|
; <1.0> 11/9/88 CCH Adding to EASE.
