    int
    db_env_create(DB_ENV **dbenvp, u_int32_t flags);

# Description

The db_env_create function creates a DB_ENV structure which is the handle for a Berkeley DB environment. A pointer to this structure is returned in the memory referenced by dbenvp.

The flags parameter must be set to 0 or the following value:

DB_CLIENT
  Create a client environment to connect to a server.

  The DB_CLIENT flag indicates to the system that this environment is remote on a server. The use of this flag causes the environment methods to use functions that call a server instead of local functions. Prior to making any environment or database method calls, the application must call the DBENV->set_server function to establish the connection to the server.

The db_env_create function returns a non-zero error value on failure and 0 on success.

# Errors

The db_env_create function 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_create function may fail and return DB_RUNRECOVERY, in which case all subsequent Berkeley DB calls will fail in the same way.
