Call any dbms-specific initialization routines.
void * Ns_PdDbInit (void);
This function is called once from the 'nspdmain' when the database driver is initialized at process startup. It normally allocates and returns a dbms-specific structure to be passed to all other routines. It also calls any dbms-specific initialization routines. This function does not open a connection to the database.
/* Things italicized would be your DBMS-specific structures and
calls. */

/* Allocate or initialize other DBMS specific data */
/* ... */
if (status == NS_ERROR) {
