Your function must return the actual number of bytes that you stored in that memory area. Returning -1 will signal an error to the library and cause it to abort the current transfer immediately. +.TP +.B CURLOPT_INFILESIZE +When uploading a file to a remote site, this option should be used to tell +libcurl what the expected size of the infile is. +.TP +.B CURLOPT_URL +The actual URL to deal with. The parameter should be a char * to a zero +terminated string. NOTE: this option is currently required! +.TP +.B CURLOPT_PROXY +If you need libcurl to use a http proxy to access the outside world, set the +proxy string with this option. The parameter should be a char * to a zero +terminated string. +.TP +.B CURLOPT_VERBOSE +Set the parameter to non-zero to get the library to display a lot of verbose +information about its operations. +.TP +.B CURLOPT_HEADER +A non-zero parameter tells the library to include the header in the +output. This is only relevant for protocols that actually has a header +preceeding the data (like HTTP). +.TP +.B CURLOPT_NOPROGRESS +A non-zero parameter tells the library to shut of the built-in progress meter +completely. (NOTE: future versions of the lib is likely to not have any +built-in progress meter at all). +.TP +.B CURLOPT_NOBODY +A non-zero parameter tells the library to not include the body-part in the +output. This is only relevant for protocols that have a separate header and +body part. +.TP +.B CURLOPT_FAILONERROR +A non-zero parameter tells the library to fail silently if the HTTP code +returned is equal or larger than 300. The default action would be to return +the page normally, ignoring that code. +.TP +.B CURLOPT_UPLOAD +A non-zero parameter tells the library to prepare for an upload. The +CURLOPT_INFILE and CURLOPT_INFILESIZE are also interesting for uploads. +.TP +.B CURLOPT_POST +A non-zero parameter tells the library to do a regular HTTP post. This is a +normal application/x-www-form-urlencoded kind, which is the most commonly used +one by HTML forms. See the CURLOPT_POSTFIELDS option for how to specify the +data to post. +.TP +.B CURLOPT_FTPLISTONLY +A non-zero parameter tells the library to just list the names of an ftp +directory, instead of doing a full directory listin that would include file +sizes, dates etc. +.TP +.B CURLOPT_FTPAPPEND +A non-zero parameter tells the library to append to the remote file instead of +overwrite it. This is only useful when uploading to a ftp site. +.TP +.B CURLOPT_NETRC +A non-zero parameter tells the library to scan your +.I ~/.netrc +file to find user name and password for the remote site you are about to +access. Do note that curl does not verify that the file has the correct +properties set (as the standard unix ftp client does), and that only machine +name, user name and password is taken into account (init macros and similar +things aren't supported). +.TP +.B CURLOPT_FOLLOWLOCATION +A non-zero parameter tells the library to follow any Location: header that the +server sends as part of a HTTP header. NOTE that this means that the library +will resend the same request on the new location and follow new Location: +headers all the way until no more such headers are returned. +.TP +.B CURLOPT_FTPASCII +A non-zero parameter tells the library to use ASCII mode for ftp transfers, +instead of the default binary transfer. This will only be useable when +transfering text data between system with different views on certain +characters, such as newlines or similar. +.TP +.B CURLOPT_PUT +A non-zero parameter tells the library to use HTTP PUT a file. The file to put +must be set with CURLOPT_INFILE and CURLOPT_INFILESIZE. +.TP +.B CURLOPT_MUTE +A non-zero parameter tells the library to be completely quiet. +.TP +.B CURLOPT_USERPWD +Pass a char * as parameter, which should be [username]:[password] to use for +the connection. If the password is left out, you will be prompted for it. +.TP +.B CURLOPT_PROXYUSERPWD +Pass a char * as parameter, which should be [username]:[password] to use for +the connection to the HTTP proxy. If the password is left out, you will be +prompted for it. +.TP +.B CURLOPT_RANGE +Pass a char * as parameter, which should contain the specified range you +want. It should be in the format "X-Y", where X or Y may be left out. The HTTP +transfers also support several intervals, separated with commas as in +.I "X-Y,N-M". +.TP +.B CURLOPT_ERRORBUFFER +Pass a char * to a buffer that the libcurl may store human readable error +messages in. This may be more helpful than just the return code from the +library. The buffer must be at least CURL_ERROR_SIZE big. +.TP +.B CURLOPT_TIMEOUT +Pass a long as parameter containing the maximum time in seconds that you allow +the libcurl transfer operation to take. Do note that normally, name lookups +maky take a considerable time and that limiting the operation to less than a +few minutes risk aborting perfectly normal operations. +.TP +.B CURLOPT_POSTFIELDS +Pass a char * as parameter, which should be the full data to post in a HTTP +post operation. See also the CURLOPT_POST. +.TP +.B CURLOPT_REFERER +Pass a pointer to a zero terminated string as parameter. It will be used to +set the referer: header in the http request sent to the remote server. This +can be used to fool servers or scripts. +.TP +.B CURLOPT_USERAGENT +Pass a pointer to a zero terminated string as parameter. It will be used to +set the user-agent: header in the http request sent to the remote server. This +can be used to fool servers or scripts. +.TP +.B CURLOPT_FTPPORT +Pass a pointer to a zero terminated string as parameter. It will be used to +get the IP address to use for the ftp PORT instruction. The PORT instruction +tells the remote server to connect to our specified IP address. The string may +be a plain IP address, a host name, an network interface name (under unix) or +just a '-' letter to let the library use your systems default IP address. +.TP +.B CURLOPT_LOW_SPEED_LIMIT +Pass a long as parameter. It contains the transfer speed in bytes per second +that the transfer should be below during CURLOPT_LOW_SPEED_TIME seconds for +the library to consider it too slow and abort. +.TP +.B CURLOPT_LOW_SPEED_TIME +Pass a long as parameter. It contains the time in seconds that the transfer +should be below the CURLOPT_LOW_SPEED_LIMIT for the library to consider it too +slow and abort. +.TP +.B CURLOPT_RESUME_FROM +Pass a long as parameter. It contains the offset in number of bytes that you +want the transfer to start from. +.TP +.B CURLOPT_COOKIE +Pass a pointer to a zero terminated string as parameter. It will be used to +set a cookie in the http request. The format of the string should be +'[NAME]=[CONTENTS];' Where NAME is the cookie name. +.TP +.B CURLOPT_HTTPHEADER +Pass a pointer to a linked list of HTTP headers to pass to the server in your +HTTP request. The linked list should be a fully valid list of 'struct +HttpHeader' structs properly filled in. TBD! +.TP +.B CURLOPT_HTTPPOST +Pass a pointer to a linked list of HTTP post data to pass to the server in +your http request. The linked list should be a fully valid list of 'struct +HttpPost' structs properly filled in. TBD! +.TP +.B CURLOPT_SSLCERT +Pass a pointer to a zero terminated string as parameter. The string should be +the file name of your certficicate in PEM format. +.TP +.B CURLOPT_SSLCERTPASSWD +Pass a pointer to a zero terminated string as parameter. It will be used as +the password required to use the CURLOPT_SSLCERT certificate. If the password +is not supplied, you will be prompted for it. +.TP +.B CURLOPT_CRLF +TBD. +.TP +.B CURLOPT_QUOTE +Pass a pointer to a linked list of FTP commands to pass to the server prior to +your ftp request. The linked list should be a fully valid list of 'struct +curl_slist' structs properly filled in. TBD! +.TP +.B CURLOPT_POSTQUOTE +Pass a pointer to a linked list of FTP commands to pass to the server after +your ftp transfer request. The linked list should be a fully valid list of +'struct curl_slist' structs properly filled in. TBD! +.TP +.B CURLOPT_WRITEHEADER +Pass a FILE * to be used to write the header part of the received data to. +.TP +.B CURLOPT_COOKIEFILE +Pass a pointer to a zero terminated string as parameter. It should contain the +name of your file holding cookie data. The cookie data may be in netscape +cookie data format or just regular HTTP-style headers dumped to a file. +.TP +.B CURLOPT_SSLVERSION +Pass a long as parameter. Set what version of SSL to attempt to use, 2 or +3. By default, the SSL library will try to solve this by itself although some +servers make this difficult why you at times will have to use this option. +.TP +.B CURLOPT_TIMECONDITION +Pass a long as parameter. This defines how the CURLOPT_TIMEVALUE time value is +treated. You can set this parameter to TIMECOND_IFMODSINCE or +TIMECOND_IFUNMODSINCE. This is aa HTTP-only feature. (TBD) +.TP +.B CURLOPT_TIMEVALUE +Pass a long as parameter. This should be the time in seconds since 1 jan 1970, +and the time will be used as specified in CURLOPT_TIMECONDITION or if that +isn't used, it will be TIMECOND_IFMODSINCE by default. +.TP +.B CURLOPT_CUSTOMREQUEST +Pass a pointer to a zero terminated string as parameter. It will be user +instead of GET or HEAD when doing the HTTP request. This is useful for doing +DELETE or other more obscure HTTP requests. Don't do this at will, make sure +your server supports the command first. +.TP +.B CURLOPT_STDERR +Pass a FILE * as parameter. This is the stream to use instead of stderr +internally when reporting errors. +.TP +.B CURLOPT_PROGRESSMODE +This is currently unsupported, and is likely to be removed in future +versions. TBD +.TP +.B CURLOPT_WRITEINFO +Pass a pointer to a zero terminated string as parameter. It will be used to +report information after a successful request. This string may contain +variables that will be substituted by their contents when output. Described +elsewhere. .PP .SH RETURN VALUE 0 means the option was set properly, non-zero means an error as |
