MONGOC_CLIENT_SELECT_SERVER(3) libmongoc MONGOC_CLIENT_SELECT_SERVER(3) SYNOPSIS mongoc_server_description_t * mongoc_client_select_server (mongoc_client_t *client, bool for_writes, const mongoc_read_prefs_t *prefs, bson_error_t *error); Choose a server for an operation, according to the logic described in the Server Selection Spec.

PARAMETERS * client: A mongoc_client_t. * for_writes: Whether to choose a server suitable for writes or reads. * prefs: An optional mongoc_read_prefs_t. If for_writes is true, prefs must be NULL. Otherwise, use prefs to customize server selection, or pass NULL to use read preference PRIMARY. * error: An optional location for a bson_error_t or NULL.
