RDITEMHDR structure (mmc.h)
The RDITEMHDR structure is introduced in MMC 1.2.
The RDITEMHDR structure is used by the RDCOMPARE structure to specify the type and cookie value of a scope or result item.
Syntax
typedef struct _RDCITEMHDR {
DWORD dwFlags;
MMC_COOKIE cookie;
LPARAM lpReserved;
} RDITEMHDR;
Members
dwFlags
A value that specifies whether the item is a scope or result item. If the RDCI_ScopeItem (0x80000000) flag is set, the item is a scope item. Otherwise, the item is a result item.
cookie
The unique identifier of the scope or result item object to be compared as part of the sorting operation.
lpReserved
Reserved for future use.
Remarks
If the snap-in implements the IResultDataCompareEx interface, MMC allocates an RDCOMPARE structure and two RDITEMHDR structures and then calls the snap-ins IResultDataCompareEx::Compare method. After the method returns, MMC releases the three structures it allocated.
