DESCRIPTION

flux_kvs_namespace_create() creates a KVS namespace. Within a namespace, users can get/put KVS values completely independent of other KVS namespaces. An owner of the namespace other than the instance owner can be chosen by setting owner. Otherwise, owner can be set to FLUX_USERID_UNKNOWN.

flux_kvs_namespace_create_with() is identical to flux_kvs_namespace_create() but will initialize the namespace to the specified rootref. This may be useful in several circumstances, such as initializing a namespace to an earlier checkpoint.

flux_kvs_namespace_remove() removes a KVS namespace.

FLAGS

The flags mask is currently unused and should be set to 0.

RETURN VALUE

flux_kvs_namespace_create() and flux_kvs_namespace_remove() return a flux_future_t on success, or NULL on failure with errno set appropriately.

ERRORS

EINVAL: One of the arguments was invalid.
ENOMEM: Out of memory.
EPROTO: A request was malformed.
ENOSYS: The KVS module is not loaded.
EEXIST: The namespace already exists.
ENOTSUP: Attempt to remove illegal namespace.
