- Adds a record into a specified Framework boot script table.
-
- This function is used to store a boot script record into a given boot

- until EFI_BOOT_SCRIPT_SAVE_PROTOCOL.CloseTable() is called. Currently, the only
- meaningful table name is EFI_ACPI_S3_RESUME_SCRIPT_TABLE. This function is
- responsible for allocating necessary memory for the script.
-
- This function has a variable parameter list. The exact parameter list depends on
- the OpCode that is passed into the function. If an unsupported OpCode or illegal
- parameter list is passed in, this function returns EFI_INVALID_PARAMETER.
- If there are not enough resources available for storing more scripts, this function returns
- EFI_OUT_OF_RESOURCES.
-
- @param This A pointer to the EFI_BOOT_SCRIPT_SAVE_PROTOCOL instance.
- @param TableName Name of the script table. Currently, the only meaningful value is
- EFI_ACPI_S3_RESUME_SCRIPT_TABLE.
- @param OpCode The operation code (opcode) number.
- @param ... Argument list that is specific to each opcode.
-
- @retval EFI_SUCCESS The operation succeeded. A record was added into the
- specified script table.
- @retval EFI_INVALID_PARAMETER The parameter is illegal or the given boot script is not supported.

- Adds a record into a specified Framework boot script table.
-
- This function is used to store a boot script record into a given boot
- script table. If the table specified by TableName is nonexistent in the
- system, a new table will automatically be created and then the script record
- will be added into the new table. A boot script table can add new script records
- until EFI_BOOT_SCRIPT_SAVE_PROTOCOL.CloseTable() is called. Currently, the only
- meaningful table name is EFI_ACPI_S3_RESUME_SCRIPT_TABLE. This function is
- responsible for allocating necessary memory for the script.
-
- This function has a variable parameter list. The exact parameter list depends on
- the OpCode that is passed into the function. If an unsupported OpCode or illegal
- parameter list is passed in, this function returns EFI_INVALID_PARAMETER.
- If there are not enough resources available for storing more scripts, this function returns
- EFI_OUT_OF_RESOURCES.
-
- @param This A pointer to the EFI_BOOT_SCRIPT_SAVE_PROTOCOL instance.
- @param TableName Name of the script table. Currently, the only meaningful value is
- EFI_ACPI_S3_RESUME_SCRIPT_TABLE.
- @param OpCode The operation code (opcode) number.
- @param ... Argument list that is specific to each opcode.
-
- @retval EFI_SUCCESS The operation succeeded. A record was added into the
- specified script table.
- @retval EFI_INVALID_PARAMETER The parameter is illegal or the given boot script is not supported.
