@param c The connection
@param only_if_exists Return a valid atom id only if the atom already exists.
@param name_len The length of the following \a name.
@param name The name of the atom.
@return A cookie
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 \a only_if_exists is 0, the atom will be created if it does not already exist.
If \a only_if_exists is 1, XCB_ATOM_NONE will be returned if the atom does
not yet exist.
