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
