mcicda: How can we get STATUS_XXX in GetLastError()?
by Francois Gouget Jan. 5, 2007

Jan. 5, 2007

In dlls/mcicda/mcicda.c we have: if (!DeviceIoControl(wmcda->handle, IOCTL_CDROM_READ_Q_CHANNEL, &fmt, sizeof(fmt), &data, sizeof(data), &br, NULL)) { if (GetLastError() == STATUS_NO_MEDIA_IN_DEVICE) mode = MCI_MODE_OPEN; However DeviceIoControl() does the following: if (status) SetLastError( RtlNtStatusToDosError(status) ); return !status; } And RtlNtStatusToDosError() converts STATUS_NO_MEDIA_IN_DEVICE to ERROR_NOT_READY. So GetLastError() cannot return STATUS_NO_MEDIA_IN_DEVICE. Or did I miss something? Maybe the right thing would be to check the return value of DeviceIoControl() rather than GetLastError()? However, in MCICDA_GetError() we have a similar check: static int MCICDA_GetError(WINE_MCICDAUDIO* wmcda) { switch (GetLastError()) { case STATUS_NO_MEDIA_IN_DEVICE: return MCIERR_DEVICE_NOT_READY; case STATUS_IO_DEVICE_ERROR: return MCIERR_HARDWARE; default: FIXME("Unknown mode %x\n", GetLastError()); } Again, as far as I can see, GetLastError() cannot return these two STATUS_XXX values so this check seems wrong. -- Francois Gouget <fgouget(a)free.fr> http://fgouget.free.fr/ Advice is what we ask for when we already know the answer but wish we didn't -- Eric Jong

rpc issues
by Matthew Edlefsen Jan. 5, 2007

Jan. 5, 2007

Hi, I've been trying to get a program that uses rpc to work on wine and I've been having some problems (my understanding is that isn't surprising). The goal is to be able to run a rpc server that sits and waits for connections over tcp/ip (It's for doing distributed computing). My first problem was that I was using RpcServerUseProtseq which after looking at the code noticed will always fail with tcp/ip since it passes RpcServerUseProtseqEp NULL for the endpoint which eventually causes rpcrt4_protseq_ncacn_ip_tcp_open_endpoint to call getaddrinfo with NULL for both the ip and port which I guess isn't allowed. Anyways I altered my code to use a given endpoint instead and now it tells me: fixme:rpc:RpcMgmtWaitServerListen not waiting for server calls to finish Does this mean the function just doesn't work? Is there any way around it? I assume if it was easy to implement it would have already but just in case what exactly needs to be done to get it working? I was also confused by the differences between the online git tree and the LXR/what actually gets downloaded to my computer. To be honest I'm pretty new to wine and linux in general but it would be absolutely wonderful to get this working. Thanks in advance - Matt Edlefsen

Winelib over Solaris/SPARC
by Keyur Pujara Jan. 5, 2007

Jan. 5, 2007

Greetings! I am contemplating to port a complex windows application using winelib over Solaris/SPARC. In one of the emails in wine-devel list, I saw that there may be following issues in the process: * byte endianness * alignment issues * pointer size * must not use x86 assembly Could someone kindly advise on whether above issues *exists* in current version of wine? How do I identify and resolve them? Thanks in advance. Keyur __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

RFC: wininet: Inconsistent use of INTERNET_SetLastError()
by Francois Gouget Jan. 5, 2007

Jan. 5, 2007

wininet has an INTERNET_SetLastError() which calls SetLastError() and does some extra tricks (see dlls/wininet/internet.c:3041). The problem is that while most functions use it, some call SetLastError() directly, seemingly without pattern or reason. Some functions even call one or the other depending on the error condition! So I propose the following patch to systematically call INTERNET_SetLastError(). However I have left the functions in cookie.c and urlcache.c unchanged as none of them calls INTERNET_SetLastError(). I have no idea if that's right or not. If I get no objection I will submit this patch to wine-patches in a few days. Otherwise I would be happy if someone could straighten this out the right way, and add explanatory comments in the places where SetLastError() should be called instead of INTERNET_SetLastError(). --- dlls/wininet/ftp.c | 2 +- dlls/wininet/http.c | 8 ++++---- dlls/wininet/internet.c | 40 ++++++++++++++++++++-------------------- 3 files changed, 25 insertions(+), 25 deletions(-) diff --git a/dlls/wininet/ftp.c b/dlls/wininet/ftp.c index 358c038..980687d 100644 --- a/dlls/wininet/ftp.c +++ b/dlls/wininet/ftp.c @@ -370,7 +370,7 @@ BOOL WINAPI FtpSetCurrentDirectoryW(HINTERNET hConnect, LPCWSTR lpszDirectory) if (!lpszDirectory) { - SetLastError(ERROR_INVALID_PARAMETER);

You could use lpRequest in asyncproc and WININET_Release and call HeapFree before return. Then workRequest may be removed. Thanks, Jacek
