SYNOPSIS

#include <sqlite3.h>

#define SQLITE_OPEN_READONLY
#define SQLITE_OPEN_READWRITE
#define SQLITE_OPEN_CREATE
#define SQLITE_OPEN_DELETEONCLOSE
#define SQLITE_OPEN_EXCLUSIVE
#define SQLITE_OPEN_AUTOPROXY
#define SQLITE_OPEN_URI
#define SQLITE_OPEN_MEMORY
#define SQLITE_OPEN_MAIN_DB
#define SQLITE_OPEN_TEMP_DB
#define SQLITE_OPEN_TRANSIENT_DB
#define SQLITE_OPEN_MAIN_JOURNAL
#define SQLITE_OPEN_TEMP_JOURNAL
#define SQLITE_OPEN_SUBJOURNAL
#define SQLITE_OPEN_SUPER_JOURNAL
#define SQLITE_OPEN_NOMUTEX

#define SQLITE_OPEN_SHAREDCACHE

#define SQLITE_OPEN_WAL
#define SQLITE_OPEN_NOFOLLOW
#define SQLITE_OPEN_EXRESCODE

DESCRIPTION

These bit values are intended for use in the 3rd parameter to the sqlite3_open_v2() interface and in the 4th parameter to the sqlite3_vfs.xOpen method.

Only those flags marked as "Ok for sqlite3_open_v2()" may be used as the third argument to the sqlite3_open_v2() interface. The other flags have historically been ignored by sqlite3_open_v2(), though future versions of SQLite might change so that an error is raised if any of the disallowed bits are passed into sqlite3_open_v2(). Applications should not depend on the historical behavior.

Note in particular that passing the SQLITE_OPEN_EXCLUSIVE flag into sqlite3_open_v2() does *not* cause the underlying database file to be opened using O_EXCL. Passing SQLITE_OPEN_EXCLUSIVE into sqlite3_open_v2() has historically be a no-op and might become an error in future versions of SQLite.

IMPLEMENTATION NOTES

These declarations were extracted from the interface documentation at line 574.
