[ofw] running ibnetdisc with the debugger attached

[Tzachi Dar]

Although running without debugger seems to be ok, we have found the following issues while running with the debugger:

Both issues in the file wm_provider.cpp

m_OverlapWrite.hEvent is being closed twice.
CWMProvider::~CWMProvider()
{
                if (m_OverlapRead.hEvent != NULL) {
                                CloseHandle(m_OverlapWrite.hEvent);
                }
                if (m_OverlapWrite.hEvent != NULL) {
                                CloseHandle(m_OverlapWrite.hEvent);
                }

Writefile is not being used according to the docs. Should be something like:

        m_OverlapWrite.Offset = 0;
        m_OverlapWrite.OffsetHigh = 0;

                                EnterCriticalSection(&m_CritSecWrite);
                                ret = WriteFile(m_hFile, pMad, bytes, &bytes, &m_OverlapWrite);
        if (ret==0) {
            if(GetLastError() == ERROR_IO_PENDING) {
                hr = GetOverlappedResult(&m_OverlapWrite, &bytes, TRUE);
            } else {
                Print()
                hr = ???
            }

The same is probably true for ReadFile.

What do you think?
