Manpages - CURLINFO_CONTENT_LENGTH_UPLOAD.3

CURLINFO_CONTENT_LENGTH_UPLOAD - get the specified size of the upload

#include <curl/curl.h>

CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_CONTENT_LENGTH_UPLOAD, double *content_length);

Pass a pointer to a double to receive the specified size of the upload. Since 7.19.4, this returns -1 if the size is not known.

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

    if(!res) {
      /* check the size */
      double cl;
      res = curl_easy_getinfo(curl, CURLINFO_CONTENT_LENGTH_UPLOAD, &cl);
      if(!res) {
        printf("Size: %.0f\n", cl);
      }
    }
  }
