[sqlite] default sqlite3 IO methods for VFS

[Ken]

Hi all,

I'm trying to implement a vfs that will disable journalling.

But i've hit a little stumbling block / learning curve.

In the vfs implementation I need to implement a sqlite3_io_methods type. 
Basically I'd like to get the default  sqlite3_io_methods and use those as part 
of my code as follows:

// IO_METHOD_OPEN
  njOpen(..) {
     if  (JOURNAL)  return ;
     
    default_IO_Open(...) ; 
 }

 // VFS call
  nonJournalOpen ( ... ) {
       static  sqlite3_io_methods njMethods   = {
                          1, 
                    njOpen, ... } ;

  }


How do I get the address of  sqlites default I/O methods?

Thanks for any suggestions.
