tdb_open - Open a tdb database.
Contents
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.
Name
tdb_open - Open a tdb database.
