man tdb_open (Fonctions bibliothèques) - Open a tdb database.
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.
