This is very strange. I do not have that on my Windows XP SP 3.
I compile and run the following program:
// pcsc.cpp : main project file.
#include "stdafx.h"
#include <stdio.h>
#include <winscard.h>
using namespace System;
int main(array<System::String ^> ^args)
{
LONG rv;
SCARDCONTEXT context;
SCARD_READERSTATE readers[2];
rv = SCardEstablishContext(SCARD_SCOPE_SYSTEM, NULL, NULL, &context);
printf("%08X\n", rv);
readers[0].szReader = L"foo";
readers[1].szReader = L"bar";
rv = SCardGetStatusChange(context, 100, readers, 2);
printf("%08X\n", rv);
rv = SCardReleaseContext(context);
printf("%08X\n", rv);
return 0;
}
And I get as output:
00000000
80100009
00000000
80100009 is SCARD_E_UNKNOWN_READER.
So I do not get SCARD_E_NO_READERS_AVAILABLE as you do.
