Prototype

int lfds711_btree_au_get_by_relative_position( struct lfds711_btree_au_element **baue,
                                               enum lfds711_btree_au_relative_position relative_position );

Parameters

struct lfds711_btree_au_element **baue

This argument is the address of a pointer to an element in a btree. Typically this pointer is initially obtained by calling lfds711_btree_au_get_by_absolute_position. This argument is then set to point to the element retrieved by the function, according to the direction argument.

enum lfds711_btree_au_relative_position relative_position

Indicates which element *baue should be moved to, using the original element pointed to by *baue as the starting point.

Return Value

Returns 1 if a btree element was found in the given direction, 0 otherwise.
