Function tskit::bindings::tsk_tree_get_parent

pub unsafe extern "C" fn tsk_tree_get_parent(
    self_: *const tsk_tree_t,
    u: tsk_id_t,
    parent: *mut tsk_id_t
) -> c_int

@brief Returns the parent of the specified node.

@rst Equivalent to tree.parent[u] with bounds checking for the node u. Performance sensitive code which can guarantee that the node u is valid should use the direct array access in preference to this method. @endrst

@param self A pointer to a tsk_tree_t object. @param u The tree node. @param parent A tsk_id_t pointer to store the returned parent node. @return 0 on success or a negative value on failure.
