/*
* acpidump - A portable utility for obtaining system ACPI tables and dumping
* them in an ASCII hex format suitable for binary extraction via acpixtract.
*
* Obtaining the system ACPI tables is an OS-specific operation.
*
* This utility can be ported to any host operating system by providing a
* module containing system-specific versions of these interfaces:
*
* AcpiOsGetTableByAddress
* AcpiOsGetTableByIndex
* AcpiOsGetTableByName
*
* See the ACPICA Reference Guide for the exact definitions of these
* interfaces. Also, see these ACPICA source code modules for example
* implementations:
*
* source/os_specific/service_layers/oswintbl.c
* source/os_specific/service_layers/oslinuxtbl.c
