How to track down an error code. GetLastError() == 64

[Gordon Scott]

Hi all,

Still working on my IOCP code, now I am getting everything zooming along up
to a certain point where CreateIoCompletionPort returns an error

GetLastError() == 64. Once this happens, ALL calls to ciop fail.
Something must be happening to cause the completion port to crash or stop
working.

Question is, For these obviously non-winsock error codes, how do I track
down what this error responds to. I see nothing in WINERROR.h that
corresponds to this...

A little more digging..

FormatMessage() returns "The specified network name is no longer
available" for error code 64.

My server is using IOCP to send roughly 1K of data to 1K simultaneous
sockets every 2 seconds.

any ideas of the cause?

You can't find it in WinError.h? In the version I have, it's on line 560...

At any rate, you can use FormatMessage() as you've done, but if you need
just a quick lookup, check out MSDN:

DOH, now I feel dumb..

I was looking for the hex value 40


Regardless, any idea what could cause this error?
