[Swig-user] Question regarding file input output (fwd)

[nastytweety <di...@cs...>]

Hello again.

I am forwarding the following message and i want to ask if something like 
that described bellow is possible.Does swig support operations like 
file-handling.I guess that swig should support whatever operations 
described in JNI.Does anybody know anything on the subject?I have to 
present an example of file management using swig java bindings till 
tuesday.Any info or/and an IDL file would be great.

Thanks
Nikolaos Diakos

Subject: [Swig-user] Question regarding file input output


Hello all.

I am trying to wrap the follow c code with java bindings.

#include <stdio.h>

struct st {
   int a;
   int b;
   int c;
};

int writeBinary(const struct st,char* f);
int readBinary(struct st *b,char* f);

int main(int argc,char* argv[])
{
   int medium = 0;
   struct st myt, it;
   struct st *ptr;

   ptr = &it;
  myt.a = 1;
   myt.b = 2;
   myt.c = 3;


   if(writeBinary(myt,argv[1]))
     exit(1);
   if((medium = readBinary(ptr,argv[1]))==0)
     exit(1);
   myt.a = medium;

  myt.b=0;
   myt.c=0;

   printf("it.a: %d\n", it.a);
   printf("it.b: %d\n", it.b);
   if(writeBinary(myt,argv[2]))
    exit(1);
}
int writeBinary(const struct st j,char* f) {
   FILE *outFile;

   if(!(outFile = fopen(f, "w")))
      return 1;

   fwrite(&j,sizeof(struct st),1,outFile);

   fclose(outFile);
   return 0;
}

int readBinary(struct st *b,char* f) {
   FILE *inFile;
   int x=0;
   if(!(inFile = fopen(f, "r")))
     return 1;
  fread((struct st *)b,sizeof(struct st),1,inFile);
   x = b->a+b->b;
   x = x+b->c;
   x = x/3;

   fclose(inFile);

   return x;
}

Unfortunatelly i haven't made it.
Can anyone give me an example of an IDL file wrapping the following code.
I am only interested in java bindings.

Thanks
Nikolaos Diakos
