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

will be added into the new 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.

EFI_OUT_OF_RESOURCES.

/**
Adds a record into S3 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. 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_S3_SAVE_STATE_PROTOCOL instance.
@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.
If the opcode is unknow or not supported because of the PCD
Feature Flags.
@retval EFI_OUT_OF_RESOURCES There is insufficient memory to store the boot script.

The opcode is inserted before or after the specified position in the boot script table. If Position is

the first opcode in the table (BeforeOrAfter is TRUE). The position which is pointed to by

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 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
