WaitForSingleObject() error codes??

I'm using WaitForSingleObject(), and at times in my program it
returns the value WAIT_FAILED. Looking at the reference page for the
function, it says to call GetLastErr() to get extended error
information. My questions is, where can I find information about the
values GetLastErr() returns when WaitForSingleObject() fails? If it
helps, I get the value 0x6 from GetLastErr().

Any help is appreciated.

ERROR_INVALID_HANDLE.
Look into WINERROR.H in your MSDEV\INCLUDE directory.

Look at the file 'winerr.h' or something like that.
It has three 'cracker' macros to extract the various parts of the error
code: severity, subsystem and code. Then you can look at the massive list
of error codes, subsystems and severities in that file to figure out what
it is.

The return values for GetLastError() are in winerror.h

Error 6 is ERROR_INVALID_HANDLE.

Take a look at FormatMessage, which will give you a printable text
error message for the normal error codes.

That's the code for an invalid handle.

You have given an invalid handle to the function. See
%MSDEV%/include/winerror.h
(where %MSDEV% is the location you installed visual C++).

Errors are listed in the SDK ( if you have MSDEV, the path is
SDKs/Win32 programmer's Reference/Appendix/Error Codes). You can also
edit the file winerror.h. 0x6L is ERROR_INVALID_HANDLE.
