--- Comment #76 from Agifem agifem@free.fr 2012-01-04 05:49:08 CST --- This is hexadecimal. 257 in decimal stands for STATUS_ALERTED (0x00000101).
The calls to WS2_recv_base always fail/terminate/abort, because it's an asynchronous socket/connexion. After aborting, it calls WS2_async_recv, the real function that does the data reception.
