https://bugs.winehq.org/show_bug.cgi?id=51529 Bug ID: 51529 Summary: CloseHandle(INVALID_HANDLE_VALUE) returns FALSE, GetLastError is ERROR_INVALID_HANDLE Product: Wine Version: 5.0 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: kernel32 Assignee: wine-bugs(a)winehq.org Reporter: sergey.bychkow(a)gmail.com Distribution: --- Created attachment 70368 --> https://bugs.winehq.org/attachment.cgi?id=70368 Test CloseHandle(INVALID_HANDLE_VALUE) CloseHandle(INVALID_HANDLE_VALUE) returns FALSE, GetLastError is ERROR_INVALID_HANDLE on Wine. I tried it with MacOSX and Linux. But on Windows CloseHandle(INVALID_HANDLE_VALUE) returns TRUE. So many programs could fail if they didn't expect FALSE here. Test case (Pascal). Can be compiled with FPC or Delphi. // file TestCloseHandle.lpr program TestCloseHandle; {$APPTYPE CONSOLE} uses //Winapi.Windows; Windows; var aHandle: THandle; aResult: HRESULT; begin //aHandle := 0; aHandle := INVALID_HANDLE_VALUE; if CloseHandle(aHandle) then aResult := 0 else aResult := GetLastError; Writeln('Result: ', aResult); end. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
