9 #include <curl/curl.h>
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.

275 NAMELOOKUP
277 CURLINFO_NAMELOOKUP_TIME and CURLINFO_NAMELOOKUP_TIME_T. The
278 time it took from the start until the name resolving was com‐
279 pleted.
280 CONNECT
282 CURLINFO_CONNECT_TIME and CURLINFO_CONNECT_TIME_T. The time it
283 took from the start until the connect to the remote host (or
284 proxy) was completed.
285 APPCONNECT
287 CURLINFO_APPCONNECT_TIME and CURLINFO_APPCONNECT_TIME_T. The
288 time it took from the start until the SSL connect/handshake with
289 the remote host was completed. (Added in 7.19.0) The latter is
290 the integer version (measuring microseconds). (Added in 7.60.0)
291 PRETRANSFER
293 CURLINFO_PRETRANSFER_TIME and CURLINFO_PRETRANSFER_TIME_T. The
294 time it took from the start until the file transfer is just
295 about to begin. This includes all pre-transfer commands and
296 negotiations that are specific to the particular protocol(s)
297 involved.
298 STARTTRANSFER
300 CURLINFO_STARTTRANSFER_TIME and CURLINFO_STARTTRANSFER_TIME_T.
301 The time it took from the start until the first byte is received
302 by libcurl.
303 TOTAL CURLINFO_TOTAL_TIME and CURLINFO_TOTAL_TIME_T. Total time of
305 the previous request.
306 REDIRECT
308 CURLINFO_REDIRECT_TIME and CURLINFO_REDIRECT_TIME_T. The time
309 it took for all redirection steps include name lookup, connect,
310 pretransfer and transfer before final transaction was started.
311 So, this is zero if no redirection took place.
312
314 If the operation was successful, CURLE_OK is returned. Otherwise an
315 appropriate error code will be returned.
