CURLINFO_SIZE_DELIVERED(3) Introduction to Library Functions

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).
