[Xen-devel] [PATCH v2 07/18] errno: add POSIX error codes EMSGSIZE, ECONNREFUSED to the ABI

[Christopher Clark <christopher.w.clark@xxxxxxxxx>]

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".
