<H2>DESCRIPTION</H2><PRE>
|
|
This man page includes most, if not all, available error
|
|
codes in libcurl. Why they occur and possibly what you
|
|
can do to fix the problem.
|
|
|
|
|
|

|
|
<H2>CURLcode</H2><PRE>
|
|
Almost all "easy" interface functions return a CURLcode
|
|
error code. No matter what, using <I>CURLOPT</I><B>_</B><I>ERRORBUFFER</I> 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.
|
|
|
|
This man page is meant to describe libcurl 7.9.6 and
|
|
later. Earlier versions might have had quirks not men-
|
|
tioned here.
|
|
|
|
CURLcode is one of the following:
|
|
|
|
<B>CURLE_OK</B> <B>(0)</B>
|
|
All fine. Proceed as usual.
|
|
|
|
<B>CURLE_UNSUPPORTED_PROTOCOL</B> <B>(1)</B>
|
|
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.
|
|
|
|
<B>CURLE_FAILED_INIT</B> <B>(2)</B>
|
|
Very early initialization code failed. This is
|
|
likely to be an internal error or problem.
|
|
|
|
<B>CURLE_URL_MALFORMAT</B> <B>(3)</B>
|
|
The URL was not properly formatted.
|
|
|
|
<B>CURLE_URL_MALFORMAT_USER</B> <B>(4)</B>
|
|
URL user malformatted. The user-part of the URL syn-
|
|
tax was not correct.
|
|
|
|
<B>CURLE_COULDNT_RESOLVE_PROXY</B> <B>(5)</B>
|
|
Couldn't resolve proxy. The given proxy host could
|
|
not be resolved.
|
|
|
|
<B>CURLE_COULDNT_RESOLVE_HOST</B> <B>(6)</B>
|
|
Couldn't resolve host. The given remote host was not
|
|
resolved.
|
|
|
|
<B>CURLE_COULDNT_CONNECT</B> <B>(7)</B>
|
|
Failed to connect() to host or proxy.
|
|
|
|
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.
|
|
|
|
<B>CURLE_FTP_ACCESS_DENIED</B> <B>(9)</B>
|
|
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.
|
|
|
|
<B>CURLE_FTP_USER_PASSWORD_INCORRECT</B> <B>(10)</B>
|
|
The username and/or the password were incorrect when
|
|
trying to login to an FTP server.
|
|
|
|
<B>CURLE_FTP_WEIRD_PASS_REPLY</B> <B>(11)</B>
|
|
After having sent the FTP password to the server,
|
|
libcurl expects a proper reply. This error code
|
|
indicates that an unexpected code was returned.
|
|
|
|
<B>CURLE_FTP_WEIRD_USER_REPLY</B> <B>(12)</B>
|
|
After having sent user name to the FTP server,
|
|
libcurl expects a proper reply. This error code
|
|
indicates that an unexpected code was returned.
|
|
|
|
<B>CURLE_FTP_WEIRD_PASV_REPLY</B> <B>(13)</B>
|
|
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.
|
|
|
|
<B>CURLE_FTP_WEIRD_227_FORMAT</B> <B>(14)</B>
|
|
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.
|
|
|
|
<B>CURLE_FTP_CANT_GET_HOST</B> <B>(15)</B>
|
|
An internal failure to lookup the host used for the
|
|
new connection.
|
|
|
|
<B>CURLE_FTP_CANT_RECONNECT</B> <B>(16)</B>
|
|
A bad return code on either PASV or EPSV was sent by
|
|
the FTP server, preventing libcurl from being able
|
|
to continue.
|
|
|
|
<B>CURLE_FTP_COULDNT_SET_BINARY</B> <B>(17)</B>
|
|
Received an error when trying to set the transfer
|
|
mode to binary.
|
|
|
|
<B>CURLE_PARTIAL_FILE</B> <B>(18)</B>
|
|
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.
|
|
This was either a weird reply to a 'RETR' command or
|
|
a zero byte transfer complete.
|
|
|
|
<B>CURLE_FTP_WRITE_ERROR</B> <B>(20)</B>
|
|
After a completed file transfer, the FTP server did
|
|
not respond a proper
|
|
|
|
|
|
<B>CURLE_FTP_QUOTE_ERROR</B> <B>(21)</B>
|
|
When sending custom "QUOTE" commands to the remote
|
|
server, one of the commands returned an error code
|
|
that was 400 or higher.
|
|
|
|
<B>CURLE_HTTP_RETURNED_ERROR</B> <B>(22)</B>
|
|
This is returned if CURLOPT_FAILONERROR is set TRUE
|
|
and the HTTP server returns an error code that is >=
|
|
400.
|
|
|
|
<B>CURLE_WRITE_ERROR</B> <B>(23)</B>
|
|
An error occurred when writing received data to a
|
|
local file, or an error was returned to libcurl from
|
|
a write callback.
|
|
|
|
<B>CURLE_MALFORMAT_USER</B> <B>(24)</B>
|
|
Malformat user. User name badly specified. *Not cur-
|
|
rently used*
|
|
|
|
<B>CURLE_FTP_COULDNT_STOR_FILE</B> <B>(25)</B>
|
|
FTP couldn't STOR file. The server denied the STOR
|
|
operation. The error buffer usually contains the
|
|
server's explanation to this.
|
|
|
|
<B>CURLE_READ_ERROR</B> <B>(26)</B>
|
|
There was a problem reading a local file or an error
|
|
returned by the read callback.
|
|
|
|
<B>CURLE_OUT_OF_MEMORY</B> <B>(27)</B>
|
|
Out of memory. A memory allocation request failed.
|
|
This is serious badness and things are severly
|
|
screwed up if this ever occur.
|
|
|
|
<B>CURLE_OPERATION_TIMEOUTED</B> <B>(28)</B>
|
|
Operation timeout. The specified time-out period was
|
|
reached according to the conditions.
|
|
|
|
<B>CURLE_FTP_COULDNT_SET_ASCII</B> <B>(29)</B>
|
|
libcurl failed to set ASCII transfer type (TYPE A).
|
|
|
|
<B>CURLE_FTP_PORT_FAILED</B> <B>(30)</B>
|
|
The FTP PORT command returned error. This mostly
|
|
happen when you haven't specified a good enough
|
|
address for libcurl to use. See <I>CURLOPT</I><B>_</B><I>FTPPORT</I>.
|
|
The FTP REST command returned error. This should
|
|
never happen if the server is sane.
|
|
|
|
<B>CURLE_FTP_COULDNT_GET_SIZE</B> <B>(32)</B>
|
|
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.
|
|
|
|
<B>CURLE_HTTP_RANGE_ERROR</B> <B>(33)</B>
|
|
The HTTP server does not support or accept range
|
|
requests.
|
|
|
|
<B>CURLE_HTTP_POST_ERROR</B> <B>(34)</B>
|
|
This is an odd error that mainly occurs due to
|
|
internal confusion.
|
|
|
|
<B>CURLE_SSL_CONNECT_ERROR</B> <B>(35)</B>
|
|
A problem occured somewhere in the SSL/TLS hand-
|
|
shake. 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.
|
|
|
|
<B>CURLE_FTP_BAD_DOWNLOAD_RESUME</B> <B>(36)</B>
|
|
Attempting FTP resume beyond file size.
|
|
|
|
<B>CURLE_FILE_COULDNT_READ_FILE</B> <B>(37)</B>
|
|
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?
|
|
|
|
<B>CURLE_LDAP_CANNOT_BIND</B> <B>(38)</B>
|
|
LDAP cannot bind. LDAP bind operation failed.
|
|
|
|
<B>CURLE_LDAP_SEARCH_FAILED</B> <B>(39)</B>
|
|
LDAP search failed.
|
|
|
|
<B>CURLE_LIBRARY_NOT_FOUND</B> <B>(40)</B>
|
|
Library not found. The LDAP library was not found.
|
|
|
|
<B>CURLE_FUNCTION_NOT_FOUND</B> <B>(41)</B>
|
|
Function not found. A required LDAP function was not
|
|
found.
|
|
|
|
<B>CURLE_ABORTED_BY_CALLBACK</B> <B>(42)</B>
|
|
Aborted by callback. A callback returned "abort" to
|
|
libcurl.
|
|
|
|
<B>CURLE_BAD_FUNCTION_ARGUMENT</B> <B>(43)</B>
|
|
Internal error. A function was called with a bad
|
|
parameter.
|
|
|
|
Internal error. A function was called in a bad
|
|
order.
|
|
|
|
<B>CURLE_HTTP_PORT_FAILED</B> <B>(45)</B>
|
|
Interface error. A specified outgoing interface
|
|
could not be used. Set which interface to use for
|
|
outgoing connections' source IP address with CUR-
|
|
LOPT_INTERFACE.
|
|
|
|
<B>CURLE_BAD_PASSWORD_ENTERED</B> <B>(46)</B>
|
|
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.
|
|
|
|
<B>CURLE_TOO_MANY_REDIRECTS</B> <B>(47)</B>
|
|
Too many redirects. When following redirects,
|
|
libcurl hit the maximum amount. Set your limit with
|
|
CURLOPT_MAXREDIRS.
|
|
|
|
<B>CURLE_UNKNOWN_TELNET_OPTION</B> <B>(48)</B>
|
|
An option set with CURLOPT_TELNETOPTIONS was not
|
|
recognized/known. Refer to the appropriate documen-
|
|
tation.
|
|
|
|
<B>CURLE_TELNET_OPTION_SYNTAX</B> <B>(49)</B>
|
|
A telnet option string was Illegally formatted.
|
|
|
|
<B>CURLE_OBSOLETE</B> <B>(50)</B>
|
|
This is not an error. This used to be another error
|
|
code in an old libcurl version and is currently
|
|
unused.
|
|
|
|
<B>CURLE_SSL_PEER_CERTIFICATE</B> <B>(51)</B>
|
|
The remote server's SSL certificate was deemed not
|
|
OK.
|
|
|
|
<B>CURLE_GOT_NOTHING</B> <B>(52)</B>
|
|
Nothing was returned from the server, and under the
|
|
circumstances, getting nothing is considered an
|
|
error.
|
|
|
|
<B>CURLE_SSL_ENGINE_NOTFOUND</B> <B>(53)</B>
|
|
The specified crypto engine wasn't found.
|
|
|
|
<B>CURLE_SSL_ENGINE_SETFAILED</B> <B>(54)</B>

|
|
|
|
Failure with receiving network data.
|
|
|
|

|
|
codes there are.
|
|
|
