669 * PARAMETERS: File - An open file for the block
670 * Filename - Filename for same, for error msg(s)
671 * Signature - ACPI signature for the block
672 * Instance - Used for multiple SSDTs in the same file
673 *

676 * DESCRIPTION: Emit the raw ASL for a complete Definition Block (DSDT or SSDT)
677 *
678 * Note: The AMLFileName parameter for DefinitionBlock is left as a NULL
679 * string. This allows the compiler to create the output AML filename from
680 * the input filename.
