I am using the API "enumports" on a Win 2000 prof(S.Pack3) PC and I am getting the error
"spoolsv.exe has generated errors and will be closed by the windows. You will need to restart the program".
This has been a problem in only few of our customer PCs and works fine in our end that makes it difficult for debugging. Here is the piece of code that is causing it
DWORD dwNeeded, dwReturned, i;
PORT_INFO_2 *pPortInfo2 = NULL;
dwNeeded=0;dwReturned = 0; i = 0;
if( EnumPorts( NULL, 2, 0, 0, &dwNeeded, &dwReturned ) == FALSE)
{
}
As soon as the EnumPorts API is executed we get the spoolsv error mentioned above.

The error u get is valid and I agree with the fact that, that is how it should work. But in my case I don't even get to the line where I check for GetLAstError. As soon as I execute the line "EnumPorts" I get the following error from the Windows spooler
"spoolsv.exe has generated errors and will be closed by the windows. You will need to restart the program"
and it stops.
And my program terminates.

So your program throws an exception? You could put the EnumPorts code in a try/catch block.
Also, you might pass the EnumPorts function the address of one PORT_INFO_2 structure. I'm wondering version of the API that is failing is mistakenly using the NULL parameter when determining the number of buffer requirement.
Folks,
I found the answer myself. It looks like an open issue from microsoft on WIndows 2000 profs.
The answer can be found in msdn

Is the error you specify the one returned by GetLastError()?
I ran your code on my machine, 2000 Prof/SP3, and it returned 0 (FALSE). GetLastError() returned 122, ERROR_INSUFFICIENT_BUFFER.
"To determine the required buffer size, call EnumPorts with cbBuf set to zero. EnumPorts fails, GetLastError returns ERROR_INSUFFICIENT_BUFFER,
I believe that this is the normal behavior when determining the buffer requirements.
Good Luck,
Steve
