Hello,
         I have used open system call in KLD to create a file. But after
inserting the module the file is not created though the file descriptor
returned is non zero. I also used close system call to close the file, usin=
g
the descriptor returned by open system call.
         I called the following function from my module:

int f_open(void)
{
   struct open_args o;
   struct close_args c;
   struct thread *td =3D curthread;
   int fd;
   o.path =3D "/home/file1.c";
   o.flags =3D O_CREAT | O_RDWR | O_APPEND;
   o.mode =3D 777;
   fd =3D open(td,&a);
   printf("\nFile descriptor  =3D %d",fd);
   c.fd =3D fd;
   close(td,&c);
}


         Can anyone help me in this regard?

TIA,
Anupam Deshpande
