See fuse-bridge.c and server-protocol.c on how to generate create()able inodes and fds. To reach the parent inode of the directory where the file needs to be created, refer the fuse_loc_fill() or server_loc_fill() functions. > data_loc.path = data_path; > data_loc.name = data_name; > > flags = O_CREAT | O_RDWR | O_EXCL; > > mode = (mode_t)0700; > > memset(fd, 0, sizeof(fd_t)); > > STACK_WIND(frame, > xlator_func_writev_create_cbk, > FIRST_CHILD(frame->this), > FIRST_CHILD(frame->this)->fops->create, > &data_loc, flags, mode, &fd); the fd pointer should be pre-allocated with fd_create(). Refer fuse_create() and fuse_create_cbk() to figure out the right things to do. If you can describe your requirements in more detail, we can suggest a few tips and directions on how to proceed. > gf_log(this->name, GF_LOG_WARNING, "Hung above me"); Avati
