Found a solution:

                        char path[PATH_MAX] = "/sys/fs/bpf/";

                        for (i = 0; i < skel->skeleton->prog_cnt; i++) {
                                snprintf(path + path_len,
                                         sizeof(path) - path_len, "%s",
                                         skel->skeleton->progs[i].name);
                                bpf_link__pin(*skel->skeleton->progs[i].link,
                                              path);
                        }
