NAME

CURLINFO_CONTENT_LENGTH_UPLOAD - get the specified size of the upload

SYNOPSIS

#include <curl/curl.h>

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

DESCRIPTION

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.

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

    if(!res) {
      /* check the size */
      double cl;
      res = curl_easy_getinfo(curl, CURLINFO_CONTENT_LENGTH_UPLOAD, &cl);

  }
