2.12.7Enum NetErrorCode

Network failure error categories.

This error codes define macro-categories of network errors that have appened. Details are available by reading the system specific net-error.

The NetError.code property assumes one of this values:

- generic: A generic failure prevented the network layer to work altogether. I.e. it was not possible to initialize the network layer

• resolv: An error happened while trying to resolve a network address; possibly, the name resolution service was not available or failed altogether.
• create: It was impossible to create the socket.
• send: The network had an error while trying to send data.
• receive: The network had an error while receiving data from a remote host.
• close: An error was detected while closing the socket. Either the socket could not be closed (i.e. because it was already invalid) or the close sequence was disrupted by a network failure.
• bind: The required address could not be allocated by the calling process. Either the address is already busy or the bind operation required privileges not owned by the process.
• accept: The network system failed while accepting an incoming connection. This usually means that the accepting thread has become unavailable.
