🦋 CURLINFO_SIZE_UPLOAD(3) 🦋

okay bestie so this one's from the libcurl Library Functions Manual and it's called CURLINFO_SIZE_UPLOAD — yes it's literally in all caps, that's just how these things roll 💅

✨ NAME ✨

CURLINFO_SIZE_UPLOAD — the number of uploaded bytes, that's the whole vibe 🎀

🌸 SYNOPSIS 🌸

#include <curl/curl.h>

CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_SIZE_UPLOAD,
                           double *uploadp);

💖 DESCRIPTION 💖

okay so here's the tea: you pass in a pointer to a double, right? And that double gets filled with the total amount of bytes that were uploaded ✨

that's it, that's the whole function, she's simple and she serves 🫶

but like… heads up bestie 👀 — CURLINFO_SIZE_DOWNLOAD... no wait, CURLINFO_SIZE_UPLOAD_T(3) is the newer replacement, and it returns a more sensible variable type. so this one's the older sister, cute but kinda dated 💀

🌈 PROTOCOLS 🌈

this functionality affects all supported protocols — every single one, no cap 👑

🧚 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) {
      double ul;
      result = curl_easy_getinfo(curl, CURLINFO_SIZE_UPLOAD, &ul);
      if(!result) {
        printf("Uploaded %.0f bytes\n", ul);
      }
    }
  }
}

like look at her go 😭 init, setopt, perform, getinfo — the whole little routine, iconic behavior fr fr 🍓

🙈 DEPRECATED 🙈

Deprecated since 7.55.0.

sad girl hours 🥲 she's been deprecated, so like… maybe use the newer one if you're starting fresh? but the info's right there if you need it 💜

⭐ AVAILABILITY ⭐

Added in curl 7.4.1 — she's an OG, been around since forever 👑

🎀 RETURN VALUE 🎀

curl_easy_getinfo(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) for the full breakdown 🔥
