| Record operations that need to be replayed during an S3 resume. | |
| This function is used to store an OpCode to be replayed as part of the S3 resume boot path. It is | |
| assumed this protocol has platform specific mechanism to store the OpCode set and replay them | |
| during the S3 resume. | |
| The opcode is inserted before or after the specified position in the boot script table. If Position is | |
| NULL then that position is after the last opcode in the table (BeforeOrAfter is TRUE) or before | |
| the first opcode in the table (BeforeOrAfter is FALSE). The position which is pointed to by | |
| Position upon return can be used for subsequent insertions. | |
| 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. | |
| OpCode values of 0x80 - 0xFE are reserved for implementation specific functions. | |
| @param[in] This A pointer to the EFI_S3_SAVE_STATE_PROTOCOL instance. | |
| @param[in] BeforeOrAfter Specifies whether the opcode is stored before (TRUE) or after (FALSE) the position | |
| in the boot script table specified by Position. If Position is NULL or points to | |
| NULL then the new opcode is inserted at the beginning of the table (if TRUE) or end | |
| of the table (if FALSE). | |
| @param[in, out] Position On entry, specifies the position in the boot script table where the opcode will be | |
| inserted, either before or after, depending on BeforeOrAfter. On exit, specifies | |
| the position of the inserted opcode in the boot script table. | |

| defined opcode types. | |
