615 parameter list is passed in, this function returns EFI_INVALID_PARAMETER.

750 Closes the specified script table.
751
752 This function closes the specified boot script table and returns the base address
753 of the table. It allocates a new pool to duplicate all the boot scripts in the specified
754 table. Once this function is called, the specified table will be destroyed after it is
755 copied into the allocated pool. As a result, any attempts to add a script record into a
756 closed table will cause a new table to be created. The base address of the allocated pool
757 will be returned in Address. After using the boot script table, the caller is responsible
758 for freeing the pool that is allocated by this function. If the boot script table,
759 such as EFI_ACPI_S3_RESUME_SCRIPT_TABLE, is required to be stored in a nonperturbed
760 memory region, the caller should copy the table into the nonperturbed memory region by itself.
