# NAME

CURLINFO_CONTENT_LENGTH_UPLOAD - specified size of the upload

# SYNOPSIS

~~~c
#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.

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 */
      double cl;
      result = curl_easy_getinfo(curl, CURLINFO_CONTENT_LENGTH_UPLOAD, &cl);
      if(result == CURLE_OK) {
        printf("Size: %.0f\n", cl);
      }
    }
  }
}
