GetSystemFirmwareTable - Why does this not work?

[ananda]

#include <windows.h>
#include <string.h>
#include <stdio.h>
#include <iostream.h>

ULONG_PTR
main(ULONG_PTR argc, char *argv[])
/*++
Description: The input to this can be

{

UCHAR pFirmwareTableBuffer1[0x100];
UCHAR pFirmwareTableBuffer2[0x100];
ULONG_PTR retValue;
ULONG_PTR err;

retValue = EnumSystemFirmwareTables('ACPI', pFirmwareTableBuffer1, 0x100);

printf("Ret vlaue 1= %d\n", retValue);

//
// Return 20 and pFirmwareTableBuffer1 has
// FACP APIC SPCR MCFG OEMB
//

retValue = GetSystemFirmwareTable('ACPI', 'FACP', pFirmwareTableBuffer2,
0x100);

err = GetLastError();
printf("Ret vlaue 2 = %d, Err = %d\n", retValue, err);

//
// Returns 0 and err = 1168 - No elements found - Why should this fail?
//

}

Please help
thanks

What a moron - you have the endian values wrong on your hex calculations for
the appropriate table offset, based on the table offset calculation section
8.3 of the ACPI 2.0 specification and later.

This is such a begineer's mistake. I can't believe the ignorance.
