25  * \ingroup nsctcp
26  *
27  * List of network stack errors that may happen in a simulation,
28  * and can be handled by the simulator in a sane way.
29  *
30  * Note that NSC handles several errors internally though
31  * nsc_assert, BUG() and friends, because they (should) never
32  * happen in a simulation (e.g. ESOCKTNOSUPPORT).
33  *
34  * These values are returned by the various methods provided by nsc.
35  * They must always be < 0, as values >= 0 are a success indicator;
36  * e.g. send_data() will return the number of bytes sent or one of
37  * the nsc_errno numbers below, accept() will return 0 on success or
38  * one of the nsc_errno numbers below, etc.
