560 | Closes the specified script table.\r | |
561 | \r | |
562 | This function closes the specified boot script table and returns the base address\r | |
563 | of the table. It allocates a new pool to duplicate all the boot scripts in the specified\r | |
564 | table. Once this function is called, the specified table will be destroyed after it is\r | |
565 | copied into the allocated pool. As a result, any attempts to add a script record into a\r | |
566 | closed table will cause a new table to be created. The base address of the allocated pool\r | |
567 | will be returned in Address. After using the boot script table, the caller is responsible\r | |
568 | for freeing the pool that is allocated by this function. If the boot script table,\r | |
569 | such as EFI_ACPI_S3_RESUME_SCRIPT_TABLE, is required to be stored in a nonperturbed\r | |
570 | memory region, the caller should copy the table into the nonperturbed memory region by itself.\r | |
