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

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.

EFI_OUT_OF_RESOURCES.

/**

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