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.
typedef struct _RDCITEMHDR {
DWORD dwFlags;
MMC_COOKIE cookie;
LPARAM lpReserved;
} RDITEMHDR;
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.
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.
