10 CURLcode curl_easy_getinfo(CURL *curl, CURLINFO info, ... );
12
15 Request internal information from the curl session with this function.
16 The third argument MUST be a pointer to a long, a pointer to a char *,
17 a pointer to a struct curl_slist * or a pointer to a double (as this
18 documentation describes further down). The data pointed-to will be
19 filled in accordingly and can be relied upon only if the function
20 returns CURLE_OK. Use this function AFTER a performed transfer if you
21 want to get transfer related data.
22 You should not free the memory returned by this function unless it is
24 explicitly mentioned below.

271 NAMELOOKUP
273 CURLINFO_NAMELOOKUP_TIME and fICURLINFO_NAMELOOKUP_TIME_T. The
274 time it took from the start until the name resolving was com‐
275 pleted.
276 CONNECT
278 CURLINFO_CONNECT_TIME and CURLINFO_CONNECT_TIME_T. The time it
279 took from the start until the connect to the remote host (or
280 proxy) was completed.
281 APPCONNECT
283 CURLINFO_APPCONNECT_TIME and CURLINFO_APPCONNECT_TIME_T. The
284 time it took from the start until the SSL connect/handshake with
285 the remote host was completed. (Added in 7.19.0) The latter is
286 the integer version (measuring microseconds). (Added in 7.60.0)
287 PRETRANSFER
289 CURLINFO_PRETRANSFER_TIME and CURLINFO_PRETRANSFER_TIME_T. The
290 time it took from the start until the file transfer is just
291 about to begin. This includes all pre-transfer commands and
292 negotiations that are specific to the particular protocol(s)
293 involved.
294 STARTTRANSFER
296 CURLINFO_STARTTRANSFER_TIME and CURLINFO_STARTTRANSFER_TIME_T.
297 The time it took from the start until the first byte is received
298 by libcurl.
299 TOTAL CURLINFO_TOTAL_TIME and CURLINFO_TOTAL_TIME_T. Total time of
301 the previous request.
302 REDIRECT
304 CURLINFO_REDIRECT_TIME and CURLINFO_REDIRECT_TIME_T. The time
305 it took for all redirection steps include name lookup, connect,
306 pretransfer and transfer before final transaction was started.
307 So, this is zero if no redirection took place.
308
310 If the operation was successful, CURLE_OK is returned. Otherwise an
311 appropriate error code will be returned.
