CURLINFO_SIZE_DOWNLOAD3
Get the number of downloaded bytes
Usage
#include <curl/curl.h> CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_SIZE_DOWNLOAD, double *dlp);
Overview
Pass a pointer to a double to receive the total amount of bytes that were downloaded. 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 and not included in this number.
CURLINFO_SIZE_DOWNLOAD_T(3) is a newer replacement that returns a more sensible variable type.
Protocols
All
Examples
int main(void)
{
CURL *curl = curl_easy_init();

CURLcode res;
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com");
/* Perform the request */
res = curl_easy_perform(curl);
if(!res) {
/* check the size */
double dl;
res = curl_easy_getinfo(curl, CURLINFO_SIZE_DOWNLOAD, &dl);
if(!res) {
printf("Downloaded %.0f bytes\n", dl);
}
}
}
}
Return value
Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
