     16 # NAME
     17 
     18 CURLINFO_CONTENT_LENGTH_UPLOAD - get the specified size of the upload
     19 
     20 # SYNOPSIS
     21 
     22 ~~~c
     23 #include <curl/curl.h>
     24 
     25 CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_CONTENT_LENGTH_UPLOAD,
     26                            double *content_length);
     27 ~~~
     28 
     29 # DESCRIPTION
     30 
     31 Pass a pointer to a double to receive the specified size of the upload. Since
     32 7.19.4, this returns -1 if the size is not known.
     33 
     34 CURLINFO_CONTENT_LENGTH_UPLOAD_T(3) is a newer replacement that returns a
     35 more sensible variable type.
