CURLINFO_PRETRANSFER_TIME_T(3)                       curl_easy_getinfo options

NAME

CURLINFO_PRETRANSFER_TIME_T - get the time until the file transfer start

SYNOPSIS

#include <curl/curl.h> CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_PRETRANSFER_TIME_T, curl_off_t *timep);

DESCRIPTION

Pass a pointer to a curl_off_t to receive the time, in microseconds, it took from the start until the file transfer is just about to begin. This includes all pre-transfer commands and negotiations that are specific to the particular protocol(s) involved. It does not involve the sending of the protocol- specific request that triggers a transfer. When a redirect is followed, the time from each request is added together. See also the TIMES overview in the curl_easy_getinfo(3) man page.

PROTOCOLS

EXAMPLE

curl = curl_easy_init(); if(curl) { curl_off_t pretransfer; curl_easy_setopt(curl, CURLOPT_URL, url); res = curl_easy_perform(curl); if(CURLE_OK == res) { res = curl_easy_getinfo(curl, CURLINFO_PRETRANSFER_TIME_T, &pretransfer); if(CURLE_OK == res) { printf("Time: %" CURL_FORMAT_CURL_OFF_T ".%06ld", pretransfer / 1000000, (long)(pretransfer % 1000000)); } } /* always cleanup */ curl_easy_cleanup(curl); }

AVAILABILITY
