Net (gb.net.curl)

This class contains important constants for use with gb.net.curl objects, especially the error code constants.

Constants

AbortedByCallback	Aborted by callback. A callback returned "abort" to libcurl.
Asynchronous	A constant for the Async property.
AuthAny	This constant is used when any authentication method is possible.
AuthAnySafe	This constant represents any authentication method, except AuthBasic.
AuthBasic	This constant represents the Basic authentication method.
AuthDigest	This constant represents the Digest authentication method.
AuthDigestIE	This constant represents the Digest authentication method with an Internet Explorer flavor.
AuthGssNegotiate	This constant represents the Gss-Negotiate authentication method.
AuthNone	This constant is used when there is no authentication method.
AuthNtlm	This constant represents the NTLM authentication method.
AuthNtlmWb	This constant represents NTLM authentication delegated to winbind helper.
BadContentEncoding	Unrecognized transfer encoding.
BadDownloadResume	Attempting FTP resume beyond file size.
BadFunctionArgument	Internal error. A function was called with a bad parameter.
ChunkFailed	Chunk callback reported error.
ConvFailed	Character conversion failed.
ConvRequired	Caller must register conversion callbacks.
FailedInit	Very early initialization code failed.
FileSizeExceeded	Maximum file size exceeded.
FtpBadFileList	Unable to parse FTP file list (during FTP wildcard downloading).
FtpPortFailed	The FTP PORT command returned error. This mostly happens when you haven't specified a good enough address for libcurl to use.
FtpPretFailed	The FTP server does not understand the PRET command at all or does not support the given argument.
FtpUnableToGetHost	An internal failure to lookup the host used for the new connection.
FtpUnableToRetrFile	This was either a weird reply to a 'RETR' command or a zero byte transfer complete.
FtpUnableToSetType	Received an error when trying to set the transfer mode to binary or ASCII.
FtpUnableToUseRest	The FTP REST command returned error. This should never happen if the server is sane.
FtpWeird227Format	FTP servers return a 227-line as a response to a PASV command. If libcurl fails to parse that line, this return code is passed back.
FtpWeirdPassReply	After having sent the FTP password to the server, libcurl expects a proper reply. This error code indicates that an unexpected code was returned.
FtpWeirdPasvReply	libcurl failed to get a sensible result back from the server as a response to either a PASV or a EPSV command. The server is flawed.
FtpWeirdServerReply	After connecting to a FTP server, libcurl expects to get a certain reply back. This error code implies that it got a strange or bad reply. The given remote server is probably not an OK FTP server.
FunctionNotFound	Function not found. A required zlib function was not found.
GotNothing	Nothing was returned from the server, and under the circumstances, getting nothing is considered an error.
HttpPostError	This is an odd error that mainly occurs due to internal confusion.
HttpReturnedError	This is returned if the HTTP server returns an error code that is >= 400.
HttpVersion10	Enforce HTTP 1.0 requests.
HttpVersion11	Enforce HTTP 1.1 requests.
HttpVersion20	Attempt HTTP 2 requests. libcurl falls back to HTTP 1.1 if HTTP 2 cannot be negotiated with the server. (Added in 7.33.0)
HttpVersion2PriorKnowledge	Issue non-TLS HTTP requests using HTTP/2 without HTTP/1.1 Upgrade. It requires prior knowledge that the server supports HTTP/2 straight away. HTTPS requests still do HTTP/2 the standard way with negotiated protocol version in the TLS handshake. (Added in 7.49.0)
HttpVersion2Tls	Attempt HTTP 2 over TLS (HTTPS) only. libcurl falls back to HTTP 1.1 if HTTP 2 cannot be negotiated with the HTTPS server. For clear text HTTP servers, libcurl uses 1.1. (Added in 7.47.0)
HttpVersion3	This option makes libcurl attempt to use HTTP/3 to the host given in the URL, with fallback to earlier HTTP versions if needed. (Added in 7.66.0)
HttpVersion3Only	Setting this makes libcurl attempt to use HTTP/3 directly to server given in the URL and does not downgrade to earlier HTTP version if the server does not support HTTP/3. (Added in 7.88.0)
HttpVersionNone	We do not care about what HTTP version the library uses. libcurl uses whatever it thinks fit.
InterfaceFailed	Interface error. A specified outgoing interface could not be used.
LoginDenied	The remote server denied curl to login.
OperationTimeout	Operation timeout. The specified time-out period was reached according to the conditions.
OutOfMemory	A memory allocation request failed. This is serious badness and things are severely screwed up if this ever occurs.
PartialFile	A file transfer was shorter or larger than expected. This happens when the server first reports an expected transfer size, and then delivers data that doesn't match the previously given size.
PeerFailedVerification	The remote server's SSL certificate or SSH md5 fingerprint was deemed not OK.
ProxyHTTP	This constant represents an HTTP proxy.
ProxySocks5	This constant represents a SOCKS5 proxy.
QuoteError	When sending custom "QUOTE" commands to the remote server, one of the commands returned an error code that was 400 or higher (for FTP) or otherwise indicated unsuccessful completion of the command.
RangeError	The server does not support or accept range requests.
ReadError	There was a problem reading a local file or an error returned by the read callback.
RecvError	Failure with receiving network data.
RemoteAccessDenied	We were denied access to the resource given in the URL.
RemoteDiskFull	Out of disk space on the server.
RemoteFileExists
RemoteFileNotFound	The resource referenced in the URL does not exist.
SendError	Failed sending network data.
SendFailRewind	When doing a send operation curl had to rewind the data to retransmit, but the rewinding operation failed.
SslCacert	Peer certificate cannot be authenticated with known CA certificates.
SslCacertBadFile	Problem with reading the SSL CA cert (path? access rights?).
SslCertProblem	Problem with the local client certificate.
SslCipher	Couldn't use specified cipher.
SslConnectError	A problem occurred somewhere in the SSL/TLS handshake. You really want the error buffer and read the message there as it pinpoints the problem slightly more. Could be certificates (file formats, paths, permissions), passwords, and others.
SslCrlBadfile	Failed to load CRL file.
SslEngineInitFailed	Initiating the SSL Engine failed.
SslEngineNotFound	The specified crypto engine wasn't found.
SslEngineSetFailed	Failed setting the selected SSL crypto engine as default!
SslIssuerError	Issuer check failed.
SslShutdownFailed	Failed to shut down the SSL connection.
Synchronous	A constant for the Async property.
TooManyRedirects	Too many redirects. When following redirects, libcurl hit the maximum amount. Set your limit with CURLOPT_MAXREDIRS.
UnableToConnect	Failed to connect() to host or proxy.
UnableToResolveHost	Couldn't resolve host. The given remote host was not resolved.
UnableToResolveProxy	Couldn't resolve proxy. The given proxy host could not be resolved.
UnsupportedProtocol	The URL you passed to libcurl used a protocol that libcurl does not support. The support might be an unused compile-time option, it can be a misspelled protocol string or just a protocol libcurl has no code for.
UploadFailed	Failed starting the upload. For FTP, the server typically denied the STOR command. The error buffer usually contains the server's explanation for this.
UrlMalformat	The URL was not properly formatted.
WriteError	An error occurred when writing received data to a local file, or an error was returned to libcurl from a write callback.

Accepting	This constant shows that a remote client is trying to connect with a server socket, and that the connection is being accepted.
Active	This constant shows that a network object is working at this moment.
CannotAuthenticate	Const CannotAuthenticate As Integer = -16
CannotBindInterface	This error constant means that binding a serversocket to a specific interface failed.
CannotBindSocket	This constant reflects that a network socket was unable to use (bind) to a port.
CannotCreateSocket	This constant reflects that a network object was unable to create a new socket, the system did not allow the operation to be performed.
CannotListen	This constant reflects that a server socket was unable to start listening on a TCP port or a local path.
CannotRead	This constant reflects that there was an error when trying to read data from a socket or a serial port.
CannotWrite	This constant shows that there was an error when trying to write data to a socket or a serial port.
Connected	This constant reflects that a socket, acting like a client, is currently connected to a remote server.
Connecting	This constant reflects that a socket, acting like a client, is trying to connect to a remote server.
ConnectionRefused	This constant reflects that a remote server refused a connection from a client socket.
ConnectionTimeout	This constant means that there was a connection timeout.
HostNotFound	This constant reflects that an object from one of the Net classes failed to translate a host name to an IP address.
IPv4	Constant used by Format for IPv4 addresses.
Inactive	This constant reflects that a network object is doing nothing, it is inactive.
Internet	Defines an Internet domain socket.
Local	Defines a local or an Unix domain socket.
Pending	This constant reflects that a remote client is trying to connect with a server socket, and that connection must be accepted or rejected.
ReceivingData	This constant means that some data is being downloaded from the network.
Searching	Reflects that an object from one of the Net classes is trying to translate a host name to an IP address.
Unix	Defines a local or Unix domain socket.

Format

Format a string that contains an IP address.
