# NAME

|

|
|
# SYNOPSIS
|
||
|
|
|
||
|
|
~~~c
|
||
|
|
#include <curl/curl.h>
|
||
|
|
|
||
|
|
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_CONTENT_LENGTH_UPLOAD,

# 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.
