QuestionVirualAlloc and ReadFile Pin
csrss1-Jun-11 8:33
Membercsrss1-Jun-11 8:33 
So, got no idea why this is not working but it simply not working.

    SIZE_T BASE_BUFFER_SIZE = 512;

BYTE * bInitialBuffer = NULL;
bInitialBuffer = (BYTE *)VirtualAlloc(0,
        BASE_BUFFER_SIZE, MEM_RESERVE, PAGE_READWRITE);

if(bInitialBuffer == NULL)
{
    // handle this
    TRACE("VirtualAlloc failed!");
    return NULL;
}
DWORD dwReadBytes;
while (FALSE != ReadFile(hDevice, bInitialBuffer, BASE_BUFFER_SIZE,
    (LPDWORD)&dwReadBytes, 0) && dwReadBytes > 0)
{
    TRACE1("got buffer! %d",dwReadBytes );
    }
    if(dwReadBytes <= 0) TRACE("failed!");


GetLAstError() returns Invalid access to memory location.
I am dealing with virtual alloc for a first time :P
What am i doing wrong?
Thanks
