NAME

       curl_easy_getinfo - Extract information from a curl session (added in 7.4)

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_getinfo(CURL *curl, CURLINFO info, ... );

DESCRIPTION

       Request internal information from the curl session with this function.  The third argument MUST be a pointer to a long, a pointer to a char
       * or a pointer to a double (as this documentation describes further down).  The data pointed-to will be filled in accordingly  and  can	be
       relied  upon  only  if the function returns CURLE_OK.  This function is intended to get used *AFTER* a performed transfer, all results from
       this function are undefined until the transfer is completed.

AVAILABLE INFORMATION

       These are informations that can be extracted:

       CURLINFO_EFFECTIVE_URL
	       Pass a pointer to a 'char *' to receive the last used effective URL.

       CURLINFO_HTTP_CODE
	       Pass a pointer to a long to receive the last received HTTP code.

       CURLINFO_FILETIME
	       Pass a pointer to a long to receive the remote time of the retrieved document. 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_FILE-
	       TIME option to curl_easy_setopt(3). (Added in 7.5)

       CURLINFO_TOTAL_TIME
	       Pass  a	pointer to a double to receive the total transaction time in seconds for the previous transfer. This time does not include
	       the connect time, so if you want the complete operation time, you should add the CURLINFO_CONNECT_TIME.

       CURLINFO_NAMELOOKUP_TIME
	       Pass a pointer to a double to receive the time, in seconds, it took from the start until the name resolving was completed.

       CURLINFO_CONNECT_TIME
	       Pass a pointer to a double to receive the time, in seconds, it took from the start until the connect to the remote host (or  proxy)
	       was completed.

       CURLINFO_PRETRANSFER_TIME
	       Pass  a pointer to a double to 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
	       Pass a pointer to a double to receive the time, in seconds, it took from the start until the first byte is just about to be  trans-
	       fered. This includes CURLINFO_PRETRANSFER_TIME and also the time the server needs to calculate the result.

       CURLINFO_REDIRECT_TIME
	       Pass  a	pointer to a double to 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 mul-
	       tiple redirections.  (Added in 7.9.7)

       CURLINFO_REDIRECT_COUNT
	       Pass a pointer to a long to receive the total number of redirections that were actually followed.  (Added in 7.9.7)

       CURLINFO_SIZE_UPLOAD
	       Pass a pointer to a double to receive the total amount of bytes that were uploaded.

       CURLINFO_SIZE_DOWNLOAD
	       Pass a pointer to a double to receive the total amount of bytes that were downloaded.

       CURLINFO_SPEED_DOWNLOAD
	       Pass a pointer to a double to receive the average download speed that curl measured for the complete download.

       CURLINFO_SPEED_UPLOAD
	       Pass a pointer to a double to receive the average upload speed that curl measured for the complete upload.

       CURLINFO_HEADER_SIZE
	       Pass a pointer to a long to receive the total size of all the headers received.

       CURLINFO_REQUEST_SIZE
	       Pass  a	pointer  to a long to 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
	       Pass a pointer to a long to receive the result of the certification verification that was requested  (using  the  CURLOPT_SSL_VERI-
	       FYPEER option to curl_easy_setopt). (Added in 7.4.2)

       CURLINFO_CONTENT_LENGTH_DOWNLOAD
	       Pass  a	pointer  to a double to receive the content-length of the download. This is the value read from the Content-Length: field.
	       (Added in 7.6.1)

       CURLINFO_CONTENT_LENGTH_UPLOAD
	       Pass a pointer to a double to receive the specified size of the upload.	(Added in 7.6.1)

       CURLINFO_CONTENT_TYPE
	       Pass a pointer to a 'char *' to 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.  (Added in 7.9.4)

RETURN VALUE

       If the operation was successful, CURLE_OK is returned. Otherwise an appropriate error code will be returned.
