Typedef Documentation

typedef u32 adj_index_t

An index for adjacencies.

Alas 'C' is not typesafe enough to b0rk when a u32 is used instead of an adi_index_t. However, for us humans, we can glean much more intent from the declaration foo bar(adj_index_t t); than we can from foo bar(u32 t);

typedef adj_walk_rc_t(* adj_walk_cb_t) (adj_index_t ai, void *ctx)
