    DBENV->set_lk_max(DB_ENV *dbenv, u_int32_t lk_max);

# Description

Set the maximum number of locks to be held or requested in the table. This value is used by DBENV->open to estimate how much space to allocate for various lock-table data structures.

If no value is specified, a default value is used.

The DBENV->set_lk_max interface may only be used to configure Berkeley DB before the DBENV->open interface is called.

The DBENV->set_lk_max function returns a non-zero error value on failure and 0 on success.

# Errors

EINVAL
  An invalid flag value or parameter was specified.

  Called after DBENV->open was called.
