TDB_OPEN(3)                                                  Linux Programmer's Manual                                                 TDB_OPEN(3)

NAME

       tdb_open - Open a tdb database.

SYNOPSIS

       #include <tdb.h>

       TDB_CONTEXT *tdb_open(const 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, instead store the data in memory. The pathname , open_flags , and mode are ignored in this case. This is useful if
              you need a quick associative array or map.

       TDB_NOLOCK
              Don't do any locking (this is always turned on for read-only file descriptors)

       TDB_NOMMAP
              Don't use mmap.

       TDB_CONVERT
              Create a database in the reverse of native endian: normally when the database is created (or cleared with TDB_CLEAR_IF_FIRST), it is
              created in native endian order.  This flag is set (or unset) automatically for existing databases.

       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.
