Igor Lauta #1 / 8	compile error ( 'struct' redefinition ) I get this error when compiling my code: c:\ntddk\src\storage\inc\ntddtape.h(97) : error C2011: '_TAPE_ERASE' : 'struct' type redefinition included files are: #include <windows.h> #include <ntddtape.h> #include <devioctl.h> #include <stdio.h> #include <stdlib.h> I saw that windef.h also has _TAPE_ERASE defined, but If I only include windows.h, then IOCTL_TAPE_SET_POSITION is not defined. how to bypass this problem ? I'm using MS VS 6 SP 5 Igor

James Brow #3 / 8	compile error ( 'struct' redefinition ) Igor, Have you read the relevant MSDN pages on the functions / definitions you are trying to use? At the bottom of every page is a requirements section which states two things: 1. which header file the definitions are located in. 2. which header file you must include Generally a definition will be located in one header file, (i.e, _TAPE_ERASE is located in ntddtape.h), BUT, the docs will state which header file to include - in almost every case you must include windows.h, and not explictly include the header file the defs are actually located in. I guess you just need to check MSDN carefully whenever something like this happens..

I didn't include defs file, just windows.h ( for various windows-specific definitons ) and ntddtape.h ( for tape ioctl's ) MSDN from October 2001 from IOCTL_TAPE_SET_POSITION MSDN info: Headers Defined in ntddtape.h; Include ntddtape.h. from TAPE_ERASE MSDN info: Requirements Windows NT/2000/XP: Included in Windows NT 3.1 and later. Header: Declared in Winnt.h; include Windows.h. now, if I include BOTH windows.h and ntddtape.h the befaviour described in my first post happens...

I would check such error before posting. regards, Igor

Claes Bergefal #5 / 8	compile error ( 'struct' redefinition ) Seems to me that you're trying to mix DDK and SDK functions. The two structures you mention both have a SDK and a DDK equivalent SDK: TAPE_ERASE TAPE_SET_POSITION DDK: IOCTL_TAPE_ERASE IOCTL_TAPE_SET_POSITION Don't mix them. If you're writing a device driver use the DDK structures, otherwise use the SDK structures Include windows.h for the SDK versions and ntddtape.h for the DDK versions /claes Quote: > > I get this error when compiling my code: > > c:\ntddk\src\storage\inc\ntddtape.h(97) : error C2011: '_TAPE_ERASE' : > > 'struct' type redefinition > > included files are: > > #include <windows.h> > > #include <ntddtape.h> > > #include <devioctl.h> > > #include <stdio.h> > > #include <stdlib.h> > > I saw that windef.h also has _TAPE_ERASE defined, but If I only include > > windows.h, > > then IOCTL_TAPE_SET_POSITION is not defined. how to bypass this problem ? > > I'm using MS VS 6 SP 5 > ok, so now I figured out that the problem is in ntddtape.h. it seams that > there is > a bug (?) in header file... > to bypass this "bug", I've copied ioctl definitons into my code, removed the > "#include <ntddtape.h>" and now it compiles and runs :) fine... > someone should fix ( or at least tell me where I'm wrong ) this. > regards, > Igor

Now I'm using IOCTL_SCSI_PASS_THROUGH_DIRECT ioctl and must include ntddscsi.h which is from DDK. regards, Igor

Claes Bergefal #7 / 8	compile error ( 'struct' redefinition ) According to KB article Q251369, DeviceIoControl together with IOCTL_SCSI_PASS_THROUGH_DIRECT is the way to do it. So I guess you should include ntddscsi.h in this case. Does it cause any problems? After studying this a bit more it seems that I was slightly mistaken. You should be able to mix DDK and SDK headers. However, I can't check on your original problem since I can't find ntddtape.h! Maybe my CD is incomplete (October 2000 Edition). I have ntddscsi.h and bunch of others, but not ntddtape.h? /claes Quote: > > Seems to me that you're trying to mix DDK and SDK functions. > > The two structures you mention both have a SDK and a DDK > > equivalent > > SDK: > > TAPE_ERASE > > TAPE_SET_POSITION > > DDK: > > IOCTL_TAPE_ERASE > > IOCTL_TAPE_SET_POSITION > > Don't mix them.

I have > ntddscsi.h and bunch of others, but not ntddtape.h? it's under /NTDDK/src/storage/inc or something like that. thx, Igor
