|
|
| A request to send or receive data |
| ||||||
|
|
|
|
| was disallowed because the socket |
| ||||||
|
|
|
|
| had already been shut down in that |
| ||||||
|
|
| Cannot | send | direction with a previous shutdown |
| ||||||
| WSAESHUTDOWN | 10058 | after | socket | call. By calling shutdown a partial |
| ||||||
|
|
| shutdown | close of a socket is requested, |
| |||||||
|
|
|
|
| which is a signal that sending or |
| ||||||
|
|
|
|
| receiving or both has been |
| ||||||

|
| The support for the specified |
| ||||||
|
|
|
|
| socket type does not exist in this |
| ||||||

| Socket type not | address family. For example, the |
| |||||||
| WSAESOCKTNOSUPPORT | 10044 | optional | type | SOCK_RAW | might |
| |||||
|
|
| supported | be selected in a socket call, and |
| |||||||
|
|
|
|
|
| |||||||
|
|
|
|
| the | implementation | does | not |
| |||
|
|
|
|
| support SOCK_RAW sockets at all. |

| |||||||
| timed out |
| of time, or established connection |
| ||||||||
|

| ||||||||
|
|
|
|
| failed because connected host has |
| ||||||
|
|
|
|
| failed to respond. |

| WSAEWOULDBLOCK | 10035 | temporarily |
