# NAME
|
|
|
|
CURLINFO_CONTENT_LENGTH_UPLOAD - get the 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.

|
# EXAMPLE

int main(void)
|
|
{
|
|
CURL *curl = curl_easy_init();
|
|
if(curl) {
|
|
CURLcode res;
|
|
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);
