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).
