[Bug 20154] New: Calling *nix Native Functions from *nix aware Windows Programs

http://bugs.winehq.org/show_bug.cgi?id=20154

           Summary: Calling *nix Native Functions from *nix aware Windows
                    Programs
           Product: Wine
           Version: 1.1.29
          Platform: PC
               URL: http://rh-software.com/
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: trivial
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs(a)winehq.org
        ReportedBy: ray(a)pobox.co.uk


I would like to call *nix native functions from SIV (http://rh-software.com/)
and I would also like to be able to run the same SIV.exe file on both native
Windows and with Wine.  I general terms I wish/need to do this to work-a-round
things that are tricky/impossible on Wine currently these mainly relate to
being unable to actually run the SIV Kernel Driver in Kernel mode.  I suspect
that from time-to-time other applications will wish to do similar.  After a
couple of false starts I think (hope) I have a solution that is acceptable.  My
basic idea is that Wine should export the following functions.

void *wine_dlopen(const char *filename, int flag); 
char *wine_dlerror(void); 
void *wine_dlsym(void *handle, const char *symbol); 
int   wine_dlclose(void *handle);

This will allow any *nix aware application to call many/most native *nix
functions without needing to created a .dll just to be able to achieve this
and/or converting the application to a full winelib application when only a
small number functions are needed.  In the case of SIV the current number is 2.

I would guess it's fairly obvious what these do.  I confirm they simply
transfer to the *nix dlopen()/dlerror()/dlsym()/dlclose().  As these are
already used internally by Wine I do not believe there should be any
portability issues.

My plan B is to create my own SIVWNE.dll that would export these functions. I
feel these will be of general use and therefore a better solution would be for
Wine to export them from one of the standard .DLLs in much the same way as it
exports wine_nt_to_unix_file_name() that allow Wine aware applications deal
with file names.

Closing. If you want a to have a conversation about this bugzilla is the worst
place for it. Creating bogus bugs won't get you anywhere. Send e-mail to
wine-devel mailing list and discuss it there.

A Winelib DLL is a much simpler solution.
