Net (gb.net.curl)

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.
