CURLINFO_SPEED_UPLOAD(3) Library Functions Manual CURLINFO_SPEED_UPLOAD(3)

CURLINFO_SPEED_UPLOAD - get upload speed

#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.

This functionality affects all supported protocols

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode res;
    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);
      }
    }
  }
}

Deprecated since 7.55.0.
