// list of network stack errors that may happen in a simulation,
// and can be handled by the simulator in a sane way.
// Note that NSC handles several errors internally though
// nsc_assert, BUG() and friends, because they (should) never
// happen in a simulation (e.g. ESOCKTNOSUPPORT).
//
// These values are returned by the various methods provided by nsc.
// They must always be < 0, as values >= 0 are a success indicator;
// e.g. send_data() will return the number of bytes sent or one of
// the nsc_errno numbers below, accept() will return 0 on success or
// one of the nsc_errno numbers below, etc.
