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. For tables installed via the EFI_ACPI_TABLE_PROTOCOL.InstallAcpiTable() interface,
|
|
the function returns the value of EFI_ACPI_STD_PROTOCOL.AcpiVersion.
|

|
|
@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.

The TableKey can be passed to EFI_ACPI_TABLE_PROTOCOL.UninstallAcpiTable()

@retval EFI_SUCCESS The function completed successfully.
