Aligns structures properly within value lists.

Syntax

void ALIGN_CLUSPROP(
   count
);

Parameters

count

Size, in bytes, of the data to align. This value must be a constant.

Return value

None

Remarks

ALIGN_CLUSPROP returns a value that is greater than or equal to count. The value represents the total byte size of the data plus the padding required for proper alignment.

ClusAPI.h defines ALIGN_CLUSPROP as follows:

#define ALIGN_CLUSPROP( count ) ((count + 3) & ~3)

Examples

The following example illustrates how to use ALIGN_CLUSPROP to calculate the size of a value list entry. For additional examples, see Using Lists and Tables.

WCHAR szData[] = L"StringData";
DWORD cbSizeofValueListEntry;

cbSizeofValueListEntry = sizeof( CLUSPROP_VALUE ) + 
                         ALIGN_CLUSPROP( sizeof( szData ) );

Requirements

Requirement	Value
