SBitMaskRestriction (Compact 7)

  • Article

3/12/2014

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.
