The FsRtlFreeExtraCreateParameter routine frees the memory for an ECP context structure.
EcpContext [in]Pointer to the extra create parameter (ECP) context structure to be freed.
If the ECP context structure to be freed is still attached to an ECP list, it must first be detached from the list by the FltRemoveExtraCreateParameter routine before the FsRtlFreeExtraCreateParameter routine can free it.
If a cleanup callback routine of type PFSRTL_EXTRA_CREATE_PARAMETER_CLEANUP_CALLBACK was defined for the given ECP context structure, this callback routine is invoked upon deletion of the ECP context structure.
