    #include <db.h>

    int
    DB_ENV->log_cursor(DB_ENV *dbenv, DB_LOGC **cursorp, u_int32_t flags);

# Description

The DB_ENV->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 DB_ENV->log_cursor method returns a non-zero error value on failure and 0 on success.

# Errors

The DB_ENV->log_cursor method may fail and return a non-zero error for the following conditions:

EINVAL
  An invalid flag value or parameter was specified.

The DB_ENV->log_cursor method may fail and return a non-zero error for errors specified for other Berkeley DB and C library or system functions. If a catastrophic error has occurred, the DB_ENV->log_cursor method may fail and return DB_RUNRECOVERY, in which case all subsequent Berkeley DB calls will fail in the same way.
