From: Andre Noll Date: Fri, 30 Dec 2022 14:08:59 +0000 (+0100) Subject: Consolidate EOF error codes. X-Git-Tag: v0.7.3~26 X-Git-Url: http://git.tue.mpg.de/?a=commitdiff_plain;h=b087c1356e3eebf656aa1c783ff7e50c9de5a229;p=paraslash.git Consolidate EOF error codes. Currently we have ~15 error codes which indicate an EOF condition. One should suffice, so drop all codes except the generic E_EOF and use that everywhere. --- diff --git a/afh_recv.c b/afh_recv.c index eebac67f..8449e787 100644 --- a/afh_recv.c +++ b/afh_recv.c @@ -205,7 +205,7 @@ static int afh_recv_post_monitor(__a_unused struct sched *s, void *context) PARA_DEBUG_LOG("adding %u bytes\n", len); btr_add_output_dont_free(start, len, btrn); } -
