pub struct InternAtomRequest<'input> {
    pub only_if_exists: bool,
    pub name: Cow<'input, [u8]>,
}
Expand description

Get atom identifier by name.

Retrieves the identifier (xcb_atom_t TODO) for the atom with the specified name. Atoms are used in protocols like EWMH, for example to store window titles (_NET_WM_NAME atom) as property of a window.

If only_if_exists is 0, the atom will be created if it does not already exist. If only_if_exists is 1, XCB_ATOM_NONE will be returned if the atom does not yet exist.

Fields

  • name - The name of the atom.
  • only_if_exists - Return a valid atom id only if the atom already exists.

Errors

  • Alloc - TODO: reasons?
  • Value - A value other than 0 or 1 was specified for only_if_exists.

  • GetAtomName: request

Example

/*
 * Resolves the _NET_WM_NAME atom.
 *
 */
void my_example(xcb_connection_t *c) {
    xcb_intern_atom_cookie_t cookie;
    xcb_intern_atom_reply_t *reply;

    cookie = xcb_intern_atom(c, 0, strlen("_NET_WM_NAME"), "_NET_WM_NAME");
    /* ... do other work here if possible ... */
    if ((reply = xcb_intern_atom_reply(c, cookie, NULL))) {
        printf("The _NET_WM_NAME atom has ID %u\n", reply->atom);
        free(reply);
    }
}
