CURLINFO_SIZE_DOWNLOAD(3) curl_easy_getinfo options CURLINFO_SIZE_DOWNLOAD(3) NAME CURLINFO_SIZE_DOWNLOAD - get the number of downloaded bytes SYNOPSIS #include <curl/curl.h> CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_SIZE_DOWNLOAD, double *dlp); DESCRIPTION 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 will be reset again for each new transfer. This counts actual payload data, what's also commonly called body. All meta and header data are excluded and will not be counted in this number. CURLINFO_SIZE_DOWNLOAD_T(3) is a newer replacement that returns a more sensible variable type. PROTOCOLS All EXAMPLE CURL *curl = curl_easy_init(); if(curl) { 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", cl); } } } AVAILABILITY Added in 7.4.1 RETURN VALUE Returns CURLE_OK if the option is supported, and CURLE_UNKNOWN_OPTION if not.
