.SH SYNOPSIS
.nf
#include <curl/curl.h>

CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_CONTENT_LENGTH_UPLOAD_T,
                           curl_off_t *content_length);
.fi
.SH DESCRIPTION
Pass a pointer to a \fIcurl_off_t\fP to receive the specified size of the
upload. Stores \-1 if the size is not known.

This is the size set by the client prior to the transfer start. The expected
upload amount. Compare this with \fICURLINFO_SIZE_UPLOAD_T(3)\fP, which is the
amount of data that was actually uploaded in the end. In many cases those two
numbers are identical.

    /* Perform the upload */
    result = curl_easy_perform(curl);

    if(result == CURLE_OK) {
      /* check the size */
