This is really not a question to consider different answers. Unix already made a (right, IMO) decision there, e.g. for read(2) syscall. If any data was actually read, the length of the consumed data must be returned, and not the error. Typically, socket functions return error on the next call, if the current call must still return data. This is why so_error is there. _______________________________________________ freebsd-net@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
