NAME

CURLINFO_CONTENT_LENGTH_UPLOAD_T - specified size of the upload

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_CONTENT_LENGTH_UPLOAD_T,
                           curl_off_t *content_length);

DESCRIPTION

Pass a pointer to a curl_off_t to receive the specified size of the upload. Stores -1 if the size is not known.

This is the size set by the client prior to the transfer start. The expected upload amount. Compare this with CURLINFO_SIZE_UPLOAD_T(3), which is the amount of data that was actually uploaded in the end. In many cases those two numbers are identical.

EXAMPLE

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

    /* Perform the upload */
    result = curl_easy_perform(curl);

    if(result == CURLE_OK) {
      /* check the size */
      curl_off_t cl;
      result = curl_easy_getinfo(curl, CURLINFO_CONTENT_LENGTH_UPLOAD_T, &cl);
      if(result == CURLE_OK) {
        printf("Upload size: %" CURL_FORMAT_CURL_OFF_T "\n", cl);
      }
    }
  }
}
