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 at winehq.org
ReportedBy: ray at 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.
