Parameters

Description:

Request internal information from the curl session with this function. The third argument will be a number, a string or an array. The data pointed-to will be filled in accordingly and can be relied upon only if the function returns CURLE_OK. Use this function AFTER a performed transfer if you want to get transfer- oriented data.
You should not free the memory returned by this function unless it is explicitly mentioned below.

AVAILABLE INFORMATION
============================
The following information can be extracted:
CURLINFO_EFFECTIVE_URL
Receive the last used effective URL.
CURLINFO_RESPONSE_CODE
Receive the last received HTTP or FTP code. This option was known as CURLINFO_HTTP_CODE in libcurl 7.10.7 and earlier. This will be zero if no server response code has been received. Note that a proxy's CONNECT response should be read with CURLINFO_HTTP_CONNECTCODE and not this.
CURLINFO_HTTP_CONNECTCODE
Receive the last received proxy response code to a CONNECT request.
CURLINFO_FILETIME
Receive the remote time of the retrieved document (in number of seconds since 1 jan 1970 in the GMT/UTC time zone). If you get -1, it can be because of many reasons (unknown, the server hides it or the server doesn't support the command that tells document time etc) and the time of the document is unknown. Note that you must tell the server to collect this information before the transfer is made, by using the CURLOPT_FILETIME option to curl_easy_setopt or you will unconditionally get a -1 back. (Added in 7.5)
CURLINFO_TOTAL_TIME
Receive the total time in seconds for the previous transfer, including name resolving, TCP connect etc.
CURLINFO_NAMELOOKUP_TIME
Receive the time, in seconds, it took from the start until the name resolving was completed.
CURLINFO_CONNECT_TIME
Receive the time, in seconds, it took from the start until the connect to the remote host (or proxy) was completed.
CURLINFO_PRETRANSFER_TIME
Receive the time, in seconds, it took from the start until the file transfer is just about to begin. This includes all pre-transfer commands and negotiations that are specific to the particular protocol(s) involved.
CURLINFO_STARTTRANSFER_TIME
Receive the time, in seconds, it took from the start until the first byte is just about to be transferred. This includes CURLINFO_PRETRANSFER_TIME and also the time the server needs to calculate the result.
CURLINFO_REDIRECT_TIME
Receive the total time, in seconds, it took for all redirection steps include name lookup, connect, pretransfer and transfer before final transaction was started. CURLINFO_REDIRECT_TIME contains the complete execution time for multiple redirections. (Added in 7.9.7)
CURLINFO_REDIRECT_COUNT
Receive the total number of redirections that were actually followed. (Added in 7.9.7)
CURLINFO_SIZE_UPLOAD
Receive the total amount of bytes that were uploaded.
CURLINFO_SIZE_DOWNLOAD
Receive the total amount of bytes that were downloaded. The amount is only for the latest transfer and will be reset again for each new transfer.
CURLINFO_SPEED_DOWNLOAD
Receive the average download speed that curl measured for the complete download.
CURLINFO_SPEED_UPLOAD
Receive the average upload speed that curl measured for the complete upload.
CURLINFO_HEADER_SIZE
Receive the total size of all the headers received.
CURLINFO_REQUEST_SIZE
Receive the total size of the issued requests. This is so far only for HTTP requests. Note that this may be more than one request if FOLLOWLOCATION is true.
CURLINFO_SSL_VERIFYRESULT
Receive the result of the certification verification that was requested (using the CURLOPT_SSL_VERIFYPEER option to curl_easy_setopt).
CURLINFO_SSL_ENGINES
Rreceive a linked-list of OpenSSL crypto-engines supported. Note that engines are normally implemented in separate dynamic libraries. Hence not all the returned engines may be available at run-time. (Added in 7.12.3)
CURLINFO_CONTENT_LENGTH_DOWNLOAD
Receive the content-length of the download. This is the value read from the Content-Length: field.
CURLINFO_CONTENT_LENGTH_UPLOAD
Receive the specified size of the upload.
CURLINFO_CONTENT_TYPE
Receive the content-type of the downloaded object. This is the value read from the Content-Type: field. If you get NULL, it means that the server didn't send a valid Content-Type header or that the protocol used doesn't support this.
CURLINFO_PRIVATE
Receive the pointer to the private data associated with the curl handle (set with the CURLOPT_PRIVATE option to curl_easy_setopt). (Added in 7.10.3)
CURLINFO_HTTPAUTH_AVAIL
Receive a bitmask indicating the authentication method(s) available. The meaning of the bits is explained in the CURLOPT_HTTPAUTH option for curl_easy_setopt. (Added in 7.10.8)
CURLINFO_PROXYAUTH_AVAIL
Receive a bitmask indicating the authentication method(s) available for your proxy authentication. (Added in 7.10.8)
CURLINFO_OS_ERRNO
Receive the errno variable from a connect failure. (Added in 7.12.2)
CURLINFO_NUM_CONNECTS
Receive how many new connections libcurl had to create to achieve the previous transfer (only the successful connects are counted). Combined with CURLINFO_REDIRECT_COUNT you are able to know how many times libcurl successfully reused existing connection(s) or not. See the Connection Options of curl_easy_setopt to see how libcurl tries to make persistent connections to save time. (Added in 7.12.3)
CURLINFO_COOKIELIST
Receive an array of all cookies cURL knows (expired ones, too). (Added in 7.14.1)
CURLINFO_LASTSOCKET
Receive the last socket used by this curl session. If the socket is no longer valid, -1 is returned. When you finish working with the socket, you must call curl_easy_cleanup() as usual and let libcurl close the socket and cleanup other resources associated with the handle. This is typically used in combination with CURLOPT_CONNECT_ONLY. (Added in 7.15.2)
CURLINFO_FTP_ENTRY_PATH
Receive a string holding the path of the entry path. That is the initial path libcurl ended up in when logging on to the remote FTP server. (Added in 7.15.4)
