IS_ALIGNED macro
The IS_ALIGNED macro determines whether the first argument is aligned on the specified power-of-2 boundary.
Syntax
IS_ALIGNED(
_pointer,
_alignment
);
Parameters
_pointer
The pointer to check for proper alignment._alignment
A power of two that specifies the alignment.
Return value
The IS_ALIGNED macro returns a value of TRUE if the pointer is properly aligned or FALSE if the pointer is not properly aligned.
Remarks
Minifilter drivers can use the IS_ALIGNED macro to verify that a pointer has the proper alignment for a 32-bit or 64-bit process. For instance, the following example verifies that the pointer is properly aligned for a 32-bit process:
if ( !IS_ALIGNED(OutputBuffer,sizeof(ULONG))) {
status = STATUS_DATATYPE_MISALIGNMENT;
break;
}
