Macro Code Message Description
WSAEISCONN 10056
Socket is
already
connected
A connect request was made on an
already connected socket. Some
implementations also return this
error if sendto is called on a
connected SOCK_DGRAM socket
(For SOCK_STREAM sockets, the
to parameter in sendto is ignored),
although other implementations
treat this as a legal occurrence.
WSAEMFILE 10024
Too many open
files
Too many open sockets. Each
implementation may have a
maximum number of socket
handles available, either globally,
per process or per thread.
WSAEMSGSIZE 10040
Message too
long
A message sent on a datagram
socket was larger than the internal
message buffer or some other
network limit, or the buffer used to
receive a datagram into was
smaller than the datagram itself.
WSAENETDOWN 10050
Network is
down
A socket operation encountered a
dead network. This could indicate a
serious failure of the network
system (i.e. the protocol stack that
the WinSock DLL runs over), the
network interface, or the local
network itself.
WSAENETRESET 10052
Network
dropped
connection on
reset
The connection has been broken
due to "keep-alive" activity
detecting a failure while the
operation was in progress. It can
also be returned by setsockopt if
an attempt is made to set
SO_KEEPALIVE on a connection
that has already failed.
WSAENETUNREACH 10051
Network is
unreachable
A socket operation was attempted
to an unreachable network. This
usually means the local software
knows no route to reach the remote
host.
WSAENOBUFS 10055
No buffer space
available
An operation on a socket could not
be performed because the system
lacked sufficient buffer space or
because a queue was full.
WSAENOPROTOOPT 10042
Bad protocol
option
An unknown, invalid or
unsupported option or level was
specified in a getsockopt or
setsockopt call.
