Golang H5Gcreate2 Examples

Example #1

File: h5g.go Project: simleb/go-hdf5

func createGroup(id C.hid_t, name string, link_flags, grp_c_flags, grp_a_flags int) (*Group, error) {
	c_name := C.CString(name)
	defer C.free(unsafe.Pointer(c_name))

	hid := C.H5Gcreate2(id, c_name, C.hid_t(link_flags), C.hid_t(grp_c_flags), P_DEFAULT.id)
	if err := h5err(C.herr_t(int(hid))); err != nil {
		return nil, err
	}
	g := &Group{Location{hid}}
	runtime.SetFinalizer(g, (*Group).finalizer)
	return g, nil
}

Example #2

File: h5g.go Project: kisielk/go-hdf5

		return nil, err
	}
	group := &Group{CommonFG{Location{Identifier{hid}}}}

}
