From 63eaa9f734e5910365bc14548df7cf91476891d7 Mon Sep 17 00:00:00 2001 From: Christopher Clark Date: Sun, 6 Jan 2019 21:05:48 -0800 Subject: [PATCH] errno: add POSIX error codes EMSGSIZE, ECONNREFUSED to the ABI EMSGSIZE: Argo's sendv operation will return EMSGSIZE when an excess amount of data, across all iovs, has been supplied, exceeding either the statically configured maximum size of a transmittable message, or the (variable) size of the ring registered by the destination domain. ECONNREFUSED: Argo's register operation will return ECONNREFUSED if a ring is being registered to communicate with a specific remote domain that does exist but is not argo-enabled. These codes are described by POSIX here: http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/errno.h.html EMSGSIZE : "Message too large" ECONNREFUSED : "Connection refused". The numeric values assigned to each are taken from Linux, as is the case for the existing error codes.
