The SBitMaskRestrictionstructure describes a bitmask restriction, which is used to perform a bitwise ANDoperation and test the result.
Syntax
struct {
ULONG
relBMR;
PT_LONG
ulPropTag;
ULONG
ulMask;
} SBitMaskRestriction;
|
Members
- relBMR
-
Relational operator describing how the mask specified in ulMaskshould be applied to the property tag. Possible values are as follows:
BMR_EQZ
Perform a bitwise ANDoperation of the mask in ulMaskwith the property represented by ulPropTagand test for being equal to zero.
BMR_NEZ
Perform a bitwise ANDoperation of the mask in ulMaskwith the property represented by ulPropTagand test for being not equal to zero.
- ulPropTag
-
Property tag of the property to which the bitmask is applied.
- ulMask
-
Bitmask to apply to the property identified by ulPropTag.
Remarks
The SBitMaskRestrictionstructure performs a bitwise ANDoperation using the bitmask described in the ulMaskmember and the value of the property described by the ulPropTagmember. If the result is zero, BMR_EQZis satisfied. If the property value has at least one of the same bits set as ulMask, BMR_NEZis satisfied.
