InterlockedAnd function (wdm.h)

The InterlockedAnd macro atomically computes a bitwise AND operation.

Syntax

LONG InterlockedAnd(
  [in, out] LONG volatile *Destination,
  [in]      LONG          Value
);

Parameters

[in, out] Destination

A pointer to the variable to be ANDed with Value. The result of the operation is stored in the variable.

[in] Value

Specifies the value to be ANDed with the variable that is pointed to by Destination.

Return value

InterlockedAnd returns the original value stored in the variable pointed to by Destination.

Remarks

InterlockedAnd atomically computes *Destination&=Value.

Interlocked operations cannot be used on non-cached memory.
