FsRtlInsertExtraCreateParameter function (ntifs.h)

The FsRtlInsertExtraCreateParameter routine inserts an extra create parameter (ECP) context structure into an ECP list.

Syntax

NTSTATUS FsRtlInsertExtraCreateParameter(
  [in, out] PECP_LIST EcpList,
  [in, out] PVOID     EcpContext
);

Parameters

[in, out] EcpList

Pointer to the ECP list structure to which the ECP context structure, pointed to by the EcpContext parameter, should be added.

[in, out] EcpContext

Pointer to the ECP context structure to be added to the ECP list, pointed to by the EcpList parameter.

Return value

FsRtlInsertExtraCreateParameter returns one of the following NTSTATUS values:

Return code Description
STATUS_SUCCESS
The given ECP context structure was successfully inserted into the given ECP list.
STATUS_INVALID_PARAMETER
The given ECP context structure already exists in the given ECP list. In the context of ECP list insertion, two ECP context structures are considered to be identical if they contain equal GUID values.

Remarks

The FsRtlInsertExtraCreateParameter routine assumes that the given ECP context structure to be inserted into the given ECP list was previously allocated by the FltAllocateExtraCreateParameter routine.

Each ECP context structure inserted into the ECP list must have a unique GUID value. This unique value is set when the ECP context structure is allocated by the FltAllocateExtraCreateParameter routine.
