NAME

       CURLINFO_QUEUE_TIME_T - time this transfer was queued

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_QUEUE_TIME_T,
                                  curl_off_t *timep);

DESCRIPTION

       Pass  a pointer to a curl_off_t to receive the time, in microseconds, this transfer was held in a waiting
       queue before it started "for real". A transfer might be put in a  queue  if  after  getting  started,  it
       cannot create a new connection etc due to set conditions and limits imposed by the application.

       See also the TIMES overview in the curl_easy_getinfo(3) man page.

PROTOCOLS

       This functionality affects all supported protocols

EXAMPLE

       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           CURLcode res;
           curl_off_t queue;
           curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
           res = curl_easy_perform(curl);
           if(CURLE_OK == res) {
             res = curl_easy_getinfo(curl, CURLINFO_QUEUE_TIME_T, &queue);
             if(CURLE_OK == res) {
               printf("Queued: %" CURL_FORMAT_CURL_OFF_T ".%06ld us", queue / 1000000,
                      (long)(queue % 1000000));
             }
           }
           /* always cleanup */
           curl_easy_cleanup(curl);
         }
       }

AVAILABILITY

       Added in curl 8.6.0
