bool mongoc_client_pool_set_server_api (mongoc_client_pool_t *pool, const mongoc_server_api_t *api, bson_error_t *error);
Set the API version to use for clients created through
pool. Once the API version is set on a pool, it may not be changed to a new value. Attempting to do so will cause this method to fail and set
True if the version was successfully set, false if not. On failure,
error will be set.
