NAME

curl_easy_setopt − set options for a curl easy handle

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLoption option, parameter);

DESCRIPTION

curl_easy_setopt() is used to tell libcurl howtobehave.Byusing the appropriate options to

curl_easy_setopt,you can change libcurl’sbehavior.All options are set with the option followed by a

parameter.That parameter can be a long,afunction pointer,an object pointer or a curl_off_t,depending

on what the speciﬁc option expects. Read this manual carefully as bad input values may cause libcurl to

behave badly! You can only set one option in each function call. A typical application uses many

curl_easy_setopt() calls in the setup phase.

Options set with this function call are valid for all forthcoming transfers performed using this handle.The

options are not in anyway reset between transfers, so if you want subsequent transfers with different

options, you must change them between the transfers. You can optionally reset all options back to internal

default with curl_easy_reset(3).

Strings passed to libcurl as ’char *’ arguments, are copied by the library; thus the string storage associated

to the pointer argument may be overwritten after curl_easy_setopt() returns. Exceptions to this rule are

described in the option details below.

NOTE: before 7.17.0 strings were not copied. Instead the user was forced keep them available until libcurl

no longer needed them.

The handle is the return code from a curl_easy_init(3) or curl_easy_duphandle(3) call.

BEHAVIOR OPTIONS

CURLOPT_VERBOSE

Set the parameter to 1 to get the library to display a lot of verbose information about its operations.

Very useful for libcurl and/or protocol debugging and understanding. The verbose information will

be sent to stderr,orthe stream set with CURLOPT_STDERR.

Youhardly everwant this set in production use, you will almost always want this when you

debug/report problems. Another neat option for debugging is the CURLOPT_DEBUGFUNCTION.

CURLOPT_HEADER

Aparameter set to 1 tells the library to include the header in the body output. This is only relevant

for protocols that actually have headers preceding the data (likeHTTP).

CURLOPT_NOPROGRESS

Aparameter set to 1 tells the library to shut offthe built-in progress meter completely.

Future versions of libcurl are likely to not have any built-in progress meter at all.

CURLOPT_NOSIGNAL

Pass a long. If it is 1, libcurl will not use anyfunctions that install signal handlers or anyfunctions

that cause signals to be sent to the process. This option is mainly here to allowmulti-threaded unix

applications to still set/use all timeout options etc, without risking getting signals. (Added in 7.10)

If this option is set and libcurl has been built with the standard name resolver,timeouts will not

occur while the name resolvetakes place. Consider building libcurl with c-ares support to enable

asynchronous DNS lookups, which enables nice timeouts for name resolves without signals.

CALLBACKOPTIONS

CURLOPT_WRITEFUNCTION

Function pointer that should match the following prototype: size_t function( void *ptr,size_t

size, size_t nmemb, void *stream); This function gets called by libcurl as soon as there is data

receivedthat needs to be saved. The size of the data pointed to by ptr is size multiplied with

nmemb,itwill not be zero terminated. Return the number of bytes actually taken care of. If that

amount differs from the amount passed to your function, it’ll signal an error to the library and it

will abort the transfer and return CURLE_WRITE_ERROR.

From 7.18.0, the function can return CURL_WRITEFUNC_PAUSE which then will cause writing

to this connection to become paused. See curl_easy_pause(3) for further details.

This function may be called with zero bytes data if the transferred ﬁle is empty.

Set this option to NULL to get the internal default function. The internal default function will

write the data to the FILE * givenwith CURLOPT_WRITEDATA.

Set the stream argument with the CURLOPT_WRITEDATA option.

The callback function will be passed as much data as possible in all invokes, but you cannot possi-

bly makeany assumptions. It may be one byte, it may be thousands. The maximum amount of data

that can be passed to the write callback is deﬁned in the curl.h header ﬁle:

CURL_MAX_WRITE_SIZE.

CURLOPT_WRITEDAT A

Data pointer to pass to the ﬁle write function. If you use the CURLOPT_WRITEFUNCTION

option, this is the pointer you’ll get as input. If you don’tuse a callback, you must pass a ’FILE *’

as libcurl will pass this to fwrite() when writing data.

The internal CURLOPT_WRITEFUNCTION will write the data to the FILE * givenwith this

option, or to stdout if this option hasn’tbeen set.

If you’re using libcurl as a win32 DLL, you MUST use the CURLOPT_WRITEFUNCTION if you

set this option or you will experience crashes.

This option is also known with the older name CURLOPT_FILE,the name CURLOPT_WRITE-

DATA wasintroduced in 7.9.7.

CURLOPT_READFUNCTION

Function pointer that should match the following prototype: size_t function( void *ptr,size_t

size, size_t nmemb, void *stream); This function gets called by libcurl as soon as it needs to read

data in order to send it to the peer.The data area pointed at by the pointer ptr may be ﬁlled with at

most size multiplied with nmemb number of bytes. Your function must return the actual number of

bytes that you stored in that memory area. Returning 0 will signal end-of-ﬁle to the library and

cause it to stop the current transfer.

If you stop the current transfer by returning 0 "pre-maturely" (i.e before the server expected it, like

when you’ve said you will upload N bytes and you upload less than N bytes), you may experience

that the server "hangs" waiting for the rest of the data that won’tcome.

The read callback may return CURL_READFUNC_ABORT to stop the current operation immedi-

ately,resulting in a CURLE_ABORTED_BY_CALLBACK error code from the transfer (Added in

7.12.1)

From 7.18.0, the function can return CURL_READFUNC_PAUSE which then will cause reading

from this connection to become paused. See curl_easy_pause(3) for further details.

libcurl 7.19.3 11 Dec 2008 2

curl_easy_setopt(3) libcurl Manual curl_easy_setopt(3)

If you set the callback pointer to NULL, or don’tset it at all, the default internal read function will

be used. It is simply doing an fread() on the FILE * stream set with CURLOPT_READDATA.

CURLOPT_READDAT A

Data pointer to pass to the ﬁle read function. If you use the CURLOPT_READFUNCTION option,

this is the pointer you’ll get as input. If you don’tspecify a read callback but instead rely on the

default internal read function, this data must be a valid readable FILE *.

If you’re using libcurl as a win32 DLL, you MUST use a CURLOPT_READFUNCTION if you set

this option.

This option was also known by the older name CURLOPT_INFILE,the name CURLOPT_READ-

DATA wasintroduced in 7.9.7.

CURLOPT_IOCTLFUNCTION

Function pointer that should match the curl_ioctl_callback prototype found in <curl/curl.h>.This

function gets called by libcurl when something special I/O-related needs to be done that the library

can’tdobyitself. For now, rewinding the read data stream is the only action it can request. The

rewinding of the read data stream may be necessary when doing a HTTP PUT or POST with a

multi-pass authentication method. (Option added in 7.12.3).

Use CURLOPT_SEEKFUNCTION instead to provide seeking!

CURLOPT_IOCTLDAT A

Pass a pointer that will be untouched by libcurl and passed as the 3rd argument in the ioctl call-

back set with CURLOPT_IOCTLFUNCTION.(Option added in 7.12.3)

CURLOPT_SEEKFUNCTION

Function pointer that should match the following prototype: int function(void *instream, curl_off_t

offset, int origin); This function gets called by libcurl to seek to a certain position in the input

stream and can be used to fast forward a ﬁle in a resumed upload (instead of reading all uploaded

bytes with the normal read function/callback). It is also called to rewind a stream when doing a

HTTP PUT or POST with a multi-pass authentication method. The function shall work like

"fseek" or "lseek" and accepted SEEK_SET,SEEK_CUR and SEEK_END as argument for origin,

although (in 7.18.0) libcurl only passes SEEK_SET.The callback must return 0 on success as

returning something else will cause the upload operation to fail.

If you forward the input arguments directly to "fseek" or "lseek", note that the data type for offset

is not the same as deﬁned for curl_off_t on manysystems! (Option added in 7.18.0)

CURLOPT_SEEKDAT A

Data pointer to pass to the ﬁle read function. If you use the CURLOPT_SEEKFUNCTION option,

this is the pointer you’ll get as input. If you don’tspecify a seek callback, NULL is passed.

(Option added in 7.18.0)

CURLOPT_SOCKOPTFUNCTION

Function pointer that should match the curl_sockopt_callback prototype found in <curl/curl.h>.

This function gets called by libcurl after the socket() call but before the connect() call. The call-

back’s purpose argument identiﬁes the exact purpose for this particular socket, and currently only

one value is supported: CURLSOCKTYPE_IPCXN for the primary connection (meaning the con-

trol connection in the FTP case). Future versions of libcurl may support more purposes. It passes

the newly created socket descriptor so additional setsockopt() calls can be done at the user’sdis-

cretion. A non-zero return code from the callback function will signal an unrecoverable error to

the library and it will close the socket and return CURLE_COULDNT_CONNECT.(Option added

in 7.15.6.)

CURLOPT_SOCKOPTDAT A

Pass a pointer that will be untouched by libcurl and passed as the ﬁrst argument in the sockopt

callback set with CURLOPT_SOCKOPTFUNCTION.(Option added in 7.15.6.)

libcurl 7.19.3 11 Dec 2008 3

curl_easy_setopt(3) libcurl Manual curl_easy_setopt(3)

CURLOPT_OPENSOCKETFUNCTION

Function pointer that should match the curl_opensocket_callback prototype found in

<curl/curl.h>.This function gets called by libcurl instead of the socket(2) call. The callback’s pur-

pose argument identiﬁes the exact purpose for this particular socket, and currently only one value

is supported: CURLSOCKTYPE_IPCXN for the primary connection (meaning the control connec-

tion in the FTP case). Future versions of libcurl may support more purposes. It passes the resolved

peer address as a address argument so the callback can modify the address or refuse to connect at

all. The callback function should return the socket or CURL_SOCKET_BAD in case no connection

should be established or anyerror detected. Anyadditional setsockopt(2) calls can be done on the

socket at the user’sdiscretion. CURL_SOCKET_BAD return value from the callback function will

signal an unrecoverable error to the library and it will return CURLE_COULDNT_CONNECT.

This return code can be used for IP address blacklisting. The default behavior is:

return socket(addr->family,addr->socktype, addr->protocol); (Option added in 7.17.1.)

CURLOPT_OPENSOCKETDAT A

Pass a pointer that will be untouched by libcurl and passed as the ﬁrst argument in the opensocket

callback set with CURLOPT_OPENSOCKETFUNCTION.(Option added in 7.17.1.)

CURLOPT_PROGRESSFUNCTION

Function pointer that should match the curl_progress_callback prototype found in <curl/curl.h>.

This function gets called by libcurl instead of its internal equivalent with a frequent interval during

operation (roughly once per second) no matter if data is being transfered or not. Unknown/unused

argument values passed to the callback will be set to zero (likeifyou only download data, the

upload size will remain 0). Returning a non-zero value from this callback will cause libcurl to

abort the transfer and return CURLE_ABORTED_BY_CALLBACK.

If you transfer data with the multi interface, this function will not be called during periods of idle-

ness unless you call the appropriate libcurl function that performs transfers.

CURLOPT_NOPROGRESS must be set to 0 to makethis function actually get called.

CURLOPT_PROGRESSDAT A

Pass a pointer that will be untouched by libcurl and passed as the ﬁrst argument in the progress

callback set with CURLOPT_PROGRESSFUNCTION.

CURLOPT_HEADERFUNCTION

Function pointer that should match the following prototype: size_t function( void *ptr,size_t size,

size_t nmemb, void *stream);.This function gets called by libcurl as soon as it has receivedheader

data. The header callback will be called once for each header and only complete header lines are

passed on to the callback. Parsing headers should be easy enough using this. The size of the data

pointed to by ptr is size multiplied with nmemb.Donot assume that the header line is zero termi-

nated! The pointer named stream is the one you set with the CURLOPT_WRITEHEADER option.

The callback function must return the number of bytes actually taken care of, or return -1 to signal

error to the library (it will cause it to abort the transfer with a CURLE_WRITE_ERROR return

code).

If this option is not set, or if it is set to NULL, but CURLOPT_HEADERDATA (CUR-

LOPT_WRITEHEADER)isset to anything but NULL, the function used to accept response data

will be used instead. That is, it will be the function speciﬁed with CURLOPT_WRITEFUNCTION,

or if it is not speciﬁed or NULL - the default, stream-writing function.

Since 7.14.1: When a server sends a chunked encoded transfer,itmay contain a trailer.That trailer

is identical to a HTTP header and if such a trailer is receiveditispassed to the application using

this callback as well. There are several ways to detect it being a trailer and not an ordinary header:

1) it comes after the response-body.2)itcomes after the ﬁnal header line (CR LF) 3) a Trailer:

header among the response-headers mention what header to expect in the trailer.

curl_easy_setopt(3) libcurl Manual curl_easy_setopt(3)

CURLOPT_WRITEHEADER

(This option is also known as CURLOPT_HEADERDAT A)Pass a pointer to be used to write the

header part of the receiveddata to. If you don’tuse your own callback to takecare of the writing,

this must be a valid FILE *. See also the CURLOPT_HEADERFUNCTION option above onhow

to set a custom get-all-headers callback.

CURLOPT_DEBUGFUNCTION

Function pointer that should match the following prototype: int curl_debug_callback(CURL *,

curl_infotype,char *, size_t, void *); CURLOPT_DEBUGFUNCTION replaces the standard

debug function used when CURLOPT_VERBOSE is in effect. This callback receivesdebug infor-

mation, as speciﬁed with the curl_infotype argument. This function must return 0. The data

pointed to by the char * passed to this function WILL NOTbezero terminated, but will be exactly

of the size as told by the size_t argument.

Av a ilable curl_infotype values:

CURLINFO_TEXT

The data is informational text.

CURLINFO_HEADER_IN

The data is header (or header-like) data receivedfrom the peer.

CURLINFO_HEADER_OUT

The data is header (or header-like) data sent to the peer.

CURLINFO_DAT A_IN

The data is protocol data receivedfrom the peer.

CURLINFO_DAT A_OUT

The data is protocol data sent to the peer.

CURLOPT_DEBUGDAT A

Pass a pointer to whateveryou want passed in to your CURLOPT_DEBUGFUNCTION in the last

void * argument. This pointer is not used by libcurl, it is only passed to the callback.

CURLOPT_SSL_CTX_FUNCTION

This option does only function for libcurl powered by OpenSSL. If libcurl was built against

another SSL library,this functionality is absent.

Function pointer that should match the following prototype: CURLcode sslctxfun(CURL *curl,

void *sslctx, void *parm); This function gets called by libcurl just before the initialization of an

SSL connection after having processed all other SSL related options to give a last chance to an

application to modify the behaviour of openssl’sssl initialization. The sslctx parameter is actually

apointer to an openssl SSL_CTX.Ifanerror is returned no attempt to establish a connection is

made and the perform operation will return the error code from this callback function. Set the

parm argument with the CURLOPT_SSL_CTX_DATA option. This option was introduced in

7.11.0.

This function will get called on all newconnections made to a server,during the SSL negotiation.

The SSL_CTX pointer will be a newone every time.

To use this properly,anon-trivial amount of knowledge of the openssl libraries is necessary.For

example, using this function allows you to use openssl callbacks to add additional validation code

for certiﬁcates, and eventochange the actual URI of an HTTPS request (example used in the

lib509 test case). See also the example section for a replacement of the key,certiﬁcate and trust

ﬁle settings.

CURLOPT_SSL_CTX_DAT A

Data pointer to pass to the ssl context callback set by the option CURLOPT_SSL_CTX_FUNC-

TION,this is the pointer you’ll get as third parameter,otherwise NULL.(Added in 7.11.0)
