CURLINFO_QUEUE_TIME_T(3) Library Functions Manual CURLINFO_QUEUE_TIME_T(3)
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.

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));
}
