# DbEnv::log_cursor

###

    #include <db_cxx.h>

    int
    DbEnv::log_cursor(DbLogc **cursorp, u_int32_t flags);

# Description

The DbEnv::log_cursor method creates a log cursor and copies a pointer to it into the memory to which cursorp refers.

The flags parameter is currently unused, and must be set to 0.

The DbEnv::log_cursor method either returns a non-zero error value or throws an exception that encapsulates a non-zero error value on failure, and returns 0 on success.

# Errors

The DbEnv::log_cursor method may fail and throw an exception or return a non-zero error for the following conditions:

EINVAL
  An invalid flag value or parameter was specified.

The DbEnv::log_cursor method may fail and throw an exception or return a non-zero error for errors specified for other Berkeley DB and C library or system methods. If a catastrophic error has occurred, the DbEnv::log_cursor method may fail and either return DB_RUNRECOVERY or throw a DbRunRecoveryException, in which case all subsequent Berkeley DB calls will fail in the same way.
