| A connect request was made on an |

| WSAEISCONN | 10056 | already |
| connected SOCK_DGRAM socket |
| |||||||
|
|
| connected |
| (For SOCK_STREAM sockets, the |
| |||||||
|
|
|
|
| to parameter in sendto is ignored), |
| |||||||
|
|
|
|
| although | other | implementations |
| |||||
|
|
|
|
| treat this as a legal occurrence. |

| Too many open sockets. Each |

|

| Too many open | implementation |
| may | have | a |

| A socket operation encountered a |

|
|
|
|
| dead network. This could indicate a |
| |||||||
| WSAENETDOWN | 10050 | Network | is | serious failure of the network |

| down |
| system (i.e. the protocol stack that |

| the WinSock DLL runs over), the |

| The connection has been broken |

| detecting a failure while the |

| An operation on a socket could not |

| WSAENOBUFS | 10055 | No buffer space | be performed because the system |
| ||||||||
| available |
| lacked sufficient buffer space or |
| |||||||||
|
