  37   Adds a record into a specified Framework boot script table.
  38
  39   This function is used to store a boot script record into a given boot
  40   script table. If the table specified by TableName is nonexistent in the
  41   system, a new table will automatically be created and then the script record
  42   will be added into the new table. A boot script table can add new script records
  43   until EFI_BOOT_SCRIPT_SAVE_PROTOCOL.CloseTable() is called. Currently, the only
  44   meaningful table name is EFI_ACPI_S3_RESUME_SCRIPT_TABLE. This function is
  45   responsible for allocating necessary memory for the script.
  46
  47   This function has a variable parameter list. The exact parameter list depends on
  48   the OpCode that is passed into the function. If an unsupported OpCode or illegal
  49   parameter list is passed in, this function returns EFI_INVALID_PARAMETER.
  50   If there are not enough resources available for storing more scripts, this function returns
  51   EFI_OUT_OF_RESOURCES.
  52
  53   @param[in]  This                 A pointer to the EFI_BOOT_SCRIPT_SAVE_PROTOCOL instance.
  54   @param[in]  TableName            Name of the script table. Currently, the only meaningful value is
  55                                    EFI_ACPI_S3_RESUME_SCRIPT_TABLE.
  56   @param[in]  OpCode               The operation code (opcode) number.
  57   @param[in]  ...                  Argument list that is specific to each opcode.
  58
  59   @retval EFI_SUCCESS              The operation succeeded. A record was added into the
  60                                    specified script table.
  61   @retval EFI_INVALID_PARAMETER    The parameter is illegal or the given boot script is not supported.
  62                                    If the opcode is unknow or not supported because of the PCD
  63                                    Feature Flags.
  64   @retval EFI_OUT_OF_RESOURCES     There is insufficient memory to store the boot script.

  77   Closes the specified script table.
  78
  79   This function closes the specified boot script table and returns the base address
  80   of the table. It allocates a new pool to duplicate all the boot scripts in the specified
  81   table. Once this function is called, the specified table will be destroyed after it is
  82   copied into the allocated pool. As a result, any attempts to add a script record into a
  83   closed table will cause a new table to be created. The base address of the allocated pool
  84   will be returned in Address. After using the boot script table, the caller is responsible
  85   for freeing the pool that is allocated by this function. If the boot script table,
  86   such as EFI_ACPI_S3_RESUME_SCRIPT_TABLE, is required to be stored in a nonperturbed
  87   memory region, the caller should copy the table into the nonperturbed memory region by itself.
