#ifdef MONGOC_ENABLE_SSL void mongoc_client_pool_set_ssl_opts (mongoc_client_pool_t *pool, const mongoc_ssl_opt_t *opts); #endif
This function is identical to mongoc_client_set_ssl_opts() except for client pools. It ensures that all clients retrieved from mongoc_client_pool_pop() or mongoc_client_pool_try_pop() are configured with the same SSL settings.
It is a programming error to call this function after retrieving a client from the client pool.
Beginning in version 1.2.0, once a pool has any SSL options set, all connections use SSL, even if ssl=true is omitted from the MongoDB URI. Before, SSL options were ignored unless ssl=true was included in the URI.
This feature requires that the MongoDB C driver was compiled with --enable-ssl.
