CURLINFO_SIZE_DELIVERED(3)                            Library Functions Manual

NAME
       CURLINFO_SIZE_DELIVERED - number of delivered bytes

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_SIZE_DELIVERED,
                                  curl_off_t *dlp);

DESCRIPTION
       Pass a pointer to a curl_off_t to receive the total amount of bytes
       that were passed on to the write callback in the download. The amount
       is only for the latest transfer and gets reset again for each new
       transfer. This counts actual payload data, what's also commonly called
       body. All meta and header data is excluded from this amount (unless
       CURLOPT_HEADER(3) is set).

       The delivered size may differ from the size retrieved with
       CURLINFO_SIZE_DOWNLOAD_T(3) when CURLOPT_ACCEPT_ENCODING(3) is used for
       automatic data decompression, as this is then the size of the
       uncompressed body while CURLINFO_SIZE_DOWNLOAD_T(3) returns the size of
       the download.

PROTOCOLS
       This functionality affects all supported protocols

EXAMPLE
       int main(void)
       {
         CURL *curl = curl_easy_init();
         if(curl) {
           CURLcode result;
           curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");

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

           if(result == CURLE_OK) {
             /* check the size */
             curl_off_t dl;
             result = curl_easy_getinfo(curl, CURLINFO_SIZE_DELIVERED, &dl);
             if(result == CURLE_OK) {
               printf("Stored %" CURL_FORMAT_CURL_OFF_T " bytes\n", dl);
             }
           }
         }
       }

AVAILABILITY
       Added in curl 8.20.0

RETURN VALUE
       curl_easy_setopt(3) returns a CURLcode indicating success or error.

       CURLE_OK (0) means everything was OK, non-zero means an error occurred,
       see libcurl-errors(3).
