Re: (tye)Re: PerlXS type problem

Thanks tye, that was an excellent help, got me going again ;-))
Now I have another problem though, one of the C functions calls another C function which returns a ULONG value. The ULONG returning function is declared as static in a .C file and takes a structure as a parameter (The structure is typedef'd in a C file aswell).
Here's what I've got so far:
testmain.XS File: This is the declaration for the ULONG returning function-

unsigned long
GetHandle(row,entry)
    unsigned long   row
    CACHE          *entry

    OUTPUT:
    RETVAL
[download]

Typemap:

const char *        T_PV
unsigned char *     T_PV
CACHE *             T_PTROBJ
[download]

When I compile this I get the following error (First of many!)
Error C2065: 'CACHE': Undeclared identifier.
I have included all headers and added all .obj files to the makefile.pl.
Is there any way around these problems?? I can't modify the c code BTW!
Again, thanks,
Paul

Sounds exactly like you aren't managing to include the definition of the CACHE struct successfully. You'll need to look at the *.c file and perhaps preprocessed output of that and dig around in the headers to figure out why. I don't think your simple typemap will work either, though. I suppose it might if there is some other function you call to initialize "entry". BTW, I'm not a big fan of T_PTROBJ. I usually prefer to stuff my C structs into Perl strings. But that is a whole 'nother topic. (: - tye (but my friends call me "Tye")	[reply]
