56 \r
57 This function is used to store an OpCode to be replayed as part of the S3 resume boot path. It is\r
58 assumed this protocol has platform specific mechanism to store the OpCode set and replay them\r
59 during the S3 resume.\r
60 The opcode is inserted before or after the specified position in the boot script table. If Position is\r
61 NULL then that position is after the last opcode in the table (BeforeOrAfter is TRUE) or before\r
62 the first opcode in the table (BeforeOrAfter is FALSE). The position which is pointed to by\r
63 Position upon return can be used for subsequent insertions.\r
64 \r
65 This function has a variable parameter list. The exact parameter list depends on the OpCode that is\r
66 passed into the function. If an unsupported OpCode or illegal parameter list is passed in, this\r
67 function returns EFI_INVALID_PARAMETER.\r
68 If there are not enough resources available for storing more scripts, this function returns\r
69 EFI_OUT_OF_RESOURCES.\r
70 OpCode values of 0x80 - 0xFE are reserved for implementation specific functions.\r
71 \r
72 @param[in] This A pointer to the EFI_S3_SAVE_STATE_PROTOCOL instance.\r
73 @param[in] BeforeOrAfter Specifies whether the opcode is stored before (TRUE) or after (FALSE) the position\r
74 in the boot script table specified by Position. If Position is NULL or points to\r
75 NULL then the new opcode is inserted at the beginning of the table (if TRUE) or end\r
76 of the table (if FALSE).\r
77 @param[in, out] Position On entry, specifies the position in the boot script table where the opcode will be\r
78 inserted, either before or after, depending on BeforeOrAfter. On exit, specifies\r
79 the position of the inserted opcode in the boot script table.\r
80 @param[in] OpCode The operation code (opcode) number. See "Related Definitions" in Write() for the\r
81 defined opcode types.\r
82 @param[in] ... Argument list that is specific to each opcode. See the following subsections for the\r
83 definition of each opcode. \r
84 \r
85 @retval EFI_SUCCESS The operation succeeded. An opcode was added into the script.\r
86 @retval EFI_INVALID_PARAMETER The Opcode is an invalid opcode value.\r
87 @retval EFI_INVALID_PARAMETER The Position is not a valid position in the boot script table.\r
88 @retval EFI_OUT_OF_RESOURCES There is insufficient memory to store the boot script table. \r
