NAME
       tdb_open - Open a tdb database.

SYNOPSIS
       #include <tdb.h>

       TDB_CONTEXT *tdb_open(char *pathname, int hash_size,
	       int tdb_flags, int open_flags, mode_t mode );


DESCRIPTION
       Open the database, creating it if necessary. The hash size
       is advisory, use zero for a default value.  tdb_flags  can
       be one of

       TDB_CLEAR_IF_FIRST
	      Clear database if we are the only one with it open.

       TDB_INTERNAL
	      Don't use a file, instaed store the data in memory.
	      The pathname , open_flags , and mode are ignored in
	      this case. This is useful if you need a quick asso-
	      ciative array or map.

       TDB_NOLOCK
	      Don't do any locking.

       TDB_NOMMAP
	      Don't use mmap.

       The  open_flags	and  mode are passed straight to the open
       call on the database file. A flags value  of  O_WRONLY  is
       invalid.

RETURN VALUE
       On  success  a  pointer	to  an	opaque	data structure, a
       TDB_CONTEXT is returned. On error a NULL is returned.
