The FltInitExtraCreateParameterLookasideList routine initializes a paged or non-paged pool lookaside list used for the allocation of one or more extra create parameter context structures (ECPs) of fixed size.
Filter [in]Opaque filter pointer to the minifilter driver. This pointer uniquely identifies the minifilter driver and remains constant as long as the minifilter driver is loaded.
Lookaside [in, out]Pointer to an opaque PAGED_LOOKASIDE_LIST or NPAGED_LOOKASIDE_LIST lookaside list-head structure. For a paged or non-paged lookaside list, the list-head structure must be allocated from non-paged pool.
Flags [in]Defines pool allocation options. If the Flags parameter contains the FSRTL_ECP_LOOKASIDE_FLAG_NONPAGED_POOL bit flag value, the routine initializes a lookaside list for non-paged ECP entries of the specified size. Otherwise, the routine initializes a lookaside list for paged ECP entries of the specified size.
Size [in]Specifies the size, in bytes, for all ECP entries in the lookaside list.
Tag [in]Specifies the pool tag to use when allocating lookaside list ECP entries. For more information about pool tags, see the Tag parameter of ExAllocatePoolWithTag.
None
Use this routine to initialize a paged or non-paged pool lookaside list. Use the FltAllocateExtraCreateParameterFromLookasideList routine to allocate an ECP from the lookaside list, and the FltFreeExtraCreateParameter routine to return an ECP buffer to the lookaside list for recycling.
Use the FltDeleteExtraCreateParameterLookasideList routine to free the lookaside list itself.
Drivers must free all ECPs and lookaside lists that they created before unloading.
For more information on using lookaside lists with drivers, see Using Lookaside Lists.
