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.

CURL *curl = curl_easy_init();
if(curl) {

curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
/* 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);
if(!res) {
printf("Size: %.0f\n", cl);
}
} }

Added in 7.6.1. Deprecated since 7.55.0.

Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
