CURLINFO_SPEED_UPLOAD - Man Page

#include <curl/curl.h>

CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_SPEED_UPLOAD, double *speed);

Pass a pointer to a double to receive the average upload speed that curl measured for the complete upload. Measured in bytes/second.

CURLINFO_SPEED_UPLOAD_T(3) is a newer replacement that returns a more sensible variable type.

CURL *curl = curl_easy_init();
if(curl) {
  curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");

  /* Perform the request */
  res = curl_easy_perform(curl);

  if(!res) {
    double speed;
    res = curl_easy_getinfo(curl, CURLINFO_SPEED_UPLOAD, &speed);
    if(!res) {
      printf("Upload speed %.0f bytes/sec\n", speed);
    }
  }
}

Added in 7.4.1. Deprecated since 7.55.0.

Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
