SQLITE3_SNAPSHOT_RECOVER(3)                           Library Functions Manual

NAME
     sqlite3_snapshot_recover - recover snapshots from a wal file

SYNOPSIS
     #include <sqlite3.h>

     int
     sqlite3_snapshot_recover(sqlite3 *db, const char *zDb);

DESCRIPTION
     If a WAL file remains on disk after all database connections close
     (either through the use of the SQLITE_FCNTL_PERSIST_WAL file control or
     because the last process to have the database opened exited without
     calling sqlite3_close()) and a new connection is subsequently opened on
     that database and WAL file, the sqlite3_snapshot_open() interface will
     only be able to open the last transaction added to the WAL file even
     though the WAL file contains other valid transactions.

     This function attempts to scan the WAL file associated with database zDb
     of database handle db and make all valid snapshots available to
     sqlite3_snapshot_open().  It is an error if there is already a read
     transaction open on the database, or if the database is not a WAL mode
     database.

     SQLITE_OK is returned if successful, or an SQLite error code otherwise.

     This interface is only available if SQLite is compiled with the
     SQLITE_ENABLE_SNAPSHOT option.

     These declarations were extracted from the interface documentation at
