| # NAME |
| |
| CURLINFO_NUM_CONNECTS - number of created connections |
| |
| # SYNOPSIS |
| |
| ~~~c |
| #include <curl/curl.h> |
| |
| CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_NUM_CONNECTS, long *nump); |
| ~~~ |
| |
| # DESCRIPTION |
| |
| Pass a pointer to a long to 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(3) you are able to know how |
| many times libcurl successfully reused existing connection(s) or not. See the |
| connection options of curl_easy_setopt(3) to see how libcurl tries to make |
| persistent connections to save time. |

| # EXAMPLE |
| |
| ~~~c |
| int main(void) |
| { |
| CURL *curl = curl_easy_init(); |
| if(curl) { |
| CURLcode res; |
| curl_easy_setopt(curl, CURLOPT_URL, "https://example.com"); |
| curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L); |
| res = curl_easy_perform(curl); |
| if(res == CURLE_OK) { |
| long connects; |
| res = curl_easy_getinfo(curl, CURLINFO_NUM_CONNECTS, &connects); |
| if(!res) |
| printf("It needed %ld connects\n", connects); |
| } |
| curl_easy_cleanup(curl); |
| } |
| } |

| # RETURN VALUE |
| |
| curl_easy_getinfo(3) returns a CURLcode indicating success or error. |
