The GetAcpiTable() function returns a pointer to a buffer containing the ACPI table associated

with the Index that was input. The following structures are not considered elements in the list of

|
ACPI tables:
|
||||||

- Root System Description Pointer (RSD_PTR)
|

|
- Root System Description Table (RSDT)
|

|
- Extended System Description Table (XSDT)
|

Version is updated with a bit map containing all the versions of ACPI of which the table is a
|

|
member.
|
||||||
|
|
||||||
|
@param[in] Index The zero-based index of the table to retrieve.
|
||||||

@param[out] Table Pointer for returning the table buffer.
|
||||||
|
@param[out] Version On return, updated with the ACPI versions to which this table belongs. Type
|
||||||
|
EFI_ACPI_TABLE_VERSION is defined in "Related Definitions" in the
|
||||||
|
EFI_ACPI_SDT_PROTOCOL.
|
||||||
|
@param[out] TableKey On return, points to the table key for the specified ACPI system definition table. This
|

|
is identical to the table key used in the EFI_ACPI_TABLE_PROTOCOL.
|

|
@retval EFI_SUCCESS The function completed successfully.
