No matter +what, using \fICURLOPT_ERRORBUFFER\fP is a good idea as it will give you a +human readable error string that may offer more details about the error cause +than just the error code does. CURLcode is one of the following: +.RS 1 +.TP 5 +.B CURLE_OK (0) +All fine. Proceed as usual. +.TP +.B CURLE_UNSUPPORTED_PROTOCOL (1) +The URL you passed to libcurl used a protocol that this libcurl does not +support. The support might be a compile-time option that you didn't use, it +can be a misspelled protocol string or just a protocol libcurl has no code +for. +.TP +.B CURLE_FAILED_INIT (2) +Very early initialization code failed. This is likely to be an internal error +or problem. +.TP +.B CURLE_URL_MALFORMAT (3) +The URL was not properly formatted. +.TP +.B CURLE_URL_MALFORMAT_USER (4) +URL user malformatted. The user-part of the URL syntax was not correct. +.TP +.B CURLE_COULDNT_RESOLVE_PROXY (5) +Couldn't resolve proxy. The given proxy host could not be resolved. +.TP +.B CURLE_COULDNT_RESOLVE_HOST (6) +Couldn't resolve host. The given remote host was not resolved. +.TP +.B CURLE_COULDNT_CONNECT (7) +Failed to connect() to host or proxy. +.TP +.B CURLE_FTP_WEIRD_SERVER_REPLY (8) +After connecting to a FTP server, libcurl expects to get a certain reply back. +This error code implies that it god a strange or bad reply. The given remote +server is probably not an OK FTP server. +.TP +.B CURLE_FTP_ACCESS_DENIED (9) +We were denied access when trying to login to an FTP server or when trying to +change working directory to the one given in the URL. +.TP +.B CURLE_FTP_USER_PASSWORD_INCORRECT (10) +The username and/or the password were incorrect when trying to login to an FTP +server. +.TP +.B CURLE_FTP_WEIRD_PASS_REPLY (11) +After having sent the FTP password to the server, libcurl expects a proper +reply. This error code indicates that an unexpected code was returned. +.TP +.B CURLE_FTP_WEIRD_USER_REPLY (12) +After having sent user name to the FTP server, libcurl expects a proper +reply. This error code indicates that an unexpected code was returned. +.TP +.B CURLE_FTP_WEIRD_PASV_REPLY (13) +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. +.TP +.B CURLE_FTP_WEIRD_227_FORMAT (14) +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. +.TP +.B CURLE_FTP_CANT_GET_HOST (15) +An internal failure to lookup the host used for the new connection. +.TP +.B CURLE_FTP_CANT_RECONNECT (16) +A bad return code on either PASV or EPSV was sent by the FTP server, +preventing libcurl from being able to continue. +.TP +.B CURLE_FTP_COULDNT_SET_BINARY (17) +Received an error when trying to set the transfer mode to binary. +.TP +.B CURLE_PARTIAL_FILE (18) +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. +.TP +.B CURLE_FTP_COULDNT_RETR_FILE (19) +This was either a weird reply to a 'RETR' command or a zero byte transfer +complete. +.TP +.B CURLE_FTP_WRITE_ERROR (20) +After a completed file transfer, the FTP server did not respond a proper +\"transfer successful\" code. +.TP +.B CURLE_FTP_QUOTE_ERROR (21) +When sending custom "QUOTE" commands to the remote server, one of the commands +returned an error code that was 400 or higher. +.TP +.B CURLE_HTTP_NOT_FOUND (22) +This is returned if CURLOPT_FAILONERROR is set TRUE and the HTTP server +returns an error code that is >= 400. +.TP +.B CURLE_WRITE_ERROR (23) +This error message is in fact used for two different kinds of write +errors. (This fact should be corrected in future versions of libcurl.) The +first kind of write this error code might refer to, is for errors that occurs +when writing received data to a local file, the other kind is when we get +problems writing data to a remote server. +.TP +.B CURLE_MALFORMAT_USER (24) +Malformat user. User name badly specified. *Not currently used* +.TP +.B CURLE_FTP_COULDNT_STOR_FILE (25) +FTP couldn't STOR file. The server denied the STOR operation. The error buffer +usually contains the server's explanation to this. +.TP +.B CURLE_READ_ERROR (26) +This error is returned both for errors when reading a local file, as well as +when getting problems when reading network data. +.TP +.B CURLE_OUT_OF_MEMORY (27) +Out of memory. A memory allocation request failed. This is serious badness and +things are severly screwed up if this ever occur. +.TP +.B CURLE_OPERATION_TIMEOUTED (28) +Operation timeout. The specified time-out period was reached according to the +conditions. +.TP +.B CURLE_FTP_COULDNT_SET_ASCII (29) +libcurl failed to set ASCII transfer type (TYPE A). +.TP +.B CURLE_FTP_PORT_FAILED (30) +The FTP PORT command returned error. This mostly happen when you haven't +specified a good enough address for libcurl to use. See \fICURLOPT_FTPPORT\fP. +.TP +.B CURLE_FTP_COULDNT_USE_REST (31) +The FTP REST command returned error. This should never happen if the server is +sane. +.TP +.B CURLE_FTP_COULDNT_GET_SIZE (32) +The FTP SIZE command returned errror. SIZE is not a kosher FTP command, it is +an extension and not all servers support it. This is not a surprising error. +.TP +.B CURLE_HTTP_RANGE_ERROR (33) +The HTTP server does not support or accept range requests. +.TP +.B CURLE_HTTP_POST_ERROR (34) +This is an odd error that mainly occurs due to internal confusion. +.TP +.B CURLE_SSL_CONNECT_ERROR (35) +A problem occured 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. +.TP +.B CURLE_FTP_BAD_DOWNLOAD_RESUME (36) +Attempting FTP resume beyond file size. +.TP +.B CURLE_FILE_COULDNT_READ_FILE (37) +A file given with FILE:// couldn't be opened. Most likely because the file +path doesn't identify an existing file. Did you check file permissions? +.TP +.B CURLE_LDAP_CANNOT_BIND (38) +LDAP cannot bind. LDAP bind operation failed. +.TP +.B CURLE_LDAP_SEARCH_FAILED (39) +LDAP search failed. +.TP +.B CURLE_LIBRARY_NOT_FOUND (40) +Library not found. The LDAP library was not found. +.TP +.B CURLE_FUNCTION_NOT_FOUND (41) +Function not found. A required LDAP function was not found. +.TP +.B CURLE_ABORTED_BY_CALLBACK (42) +Aborted by callback. A callback returned "abort" to libcurl. +.TP +.B CURLE_BAD_FUNCTION_ARGUMENT (43) +Internal error. A function was called with a bad parameter. +.TP +.B CURLE_BAD_CALLING_ORDER (44) +Internal error. A function was called in a bad order. +.TP +.B CURLE_HTTP_PORT_FAILED (45) +Interface error. A specified outgoing interface could not be used. Set which +interface to use for outgoing connections' source IP address with +CURLOPT_INTERFACE. +.TP +.B CURLE_BAD_PASSWORD_ENTERED (46) +Bad password entered. An error was signaled when the password was +entered. This can also be the result of a "bad password" returned from a +specified password callback. +.TP +.B CURLE_TOO_MANY_REDIRECTS (47) +Too many redirects. When following redirects, libcurl hit the maximum amount. +Set your limit with CURLOPT_MAXREDIRS. +.TP +.B CURLE_UNKNOWN_TELNET_OPTION (48) +An option set with CURLOPT_TELNETOPTIONS was not recognized/known. Refer to +the appropriate documentation. +.TP +.B CURLE_TELNET_OPTION_SYNTAX (49) +A telnet option string was Illegally formatted. +.TP +.B CURLE_OBSOLETE (50) +This is not an error. This used to be another error code in an old libcurl +version and is currently unused. +.TP +.B CURLE_SSL_PEER_CERTIFICATE (51) +The remote server's SSL certificate was deemed not OK. +.TP +.B CURLE_GOT_NOTHING (52) +Nothing was returned from the server, and under the circumstances, getting +nothing is considered an error. +.TP +.B CURLE_SSL_ENGINE_NOTFOUND (53) +The specified crypto engine wasn't found. +.TP +.B CURLE_SSL_ENGINE_SETFAILED (54) +Failed setting the selected SSL crypto engine as default! + +.TP +.B CURL_LAST +This is not an error, but in the curl/curl.h file this can be used to know how +many existing error codes there are. +.RE + +.SH "CURLMcode" +This is the generic return code used by functions in the libcurl multi +interface. |
