RFR 8037274 (Round 0): sun.tools.attach.WindowsVirtualMachine#createPipe() needs more descriptive message when pipe creation fails

[Peter Allwin]

Hi Jaroslav,

You could use the FormatMessage function which produces a text message for GetLastError, the os::lasterror function in os_windows.cpp does just that.

The fix is pretty simple but the code I produced might not be exactly aligned with the general C coding style in JDK source base. If you see any violation, please, let me know.
