SBitMaskRestriction
The SBitMaskRestriction structure describes a bitmask restriction, which is used to perform a bitwise AND operation and test the result.
Syntax
struct {
ULONG relBMR;
PT_LONG ulPropTag;
ULONG ulMask;
} SBitMaskRestriction;
Members
relBMR
Relational operator describing how the mask specified in ulMask should be applied to the property tag. Possible values are as follows:BMR_EQZ
Perform a bitwise AND operation of the mask in ulMask with the property represented by ulPropTag and test for being equal to zero.
BMR_NEZ
Perform a bitwise AND operation of the mask in ulMask with the property represented by ulPropTag and 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 SBitMaskRestriction structure performs a bitwise AND operation using the bitmask described in the ulMask member and the value of the property described by the ulPropTag member. If the result is zero, BMR_EQZ is satisfied. If the property value has at least one of the same bits set as ulMask, BMR_NEZ is satisfied.
