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:
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 handle contains a special field, "app_private", which
is declared as type "void *". This field is provided for the use of
the application program. It is initialized to NULL and is not further
used by Berkeley DB in any way.
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.
