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);

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