🎀 NAME 🎀

CURLINFO_RTSP_CSEQ_RECV — last received RTSP CSeq. That's the whole vibe. 🫶

🌸 SYNOPSIS 🌸

#include <curl/curl.h>

CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_RTSP_CSEQ_RECV, long *cseq);

💖 DESCRIPTION 💖

You pass a pointer to a long, and it receives the most recently received CSeq from the server. No cap. If your application encounters a CURLE_RTSP_CSEQ_ERROR, then you may wish to troubleshoot and/or fix the CSeq mismatch by peeking at this value. Like, it's giving debug-info bestie. 👀💅

🦋 PROTOCOLS 🦋

This functionality affects rtsp only. Periodt. 💜

🌈 EXAMPLE 🌈

Here's the code, bestie:

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode result;
    curl_easy_setopt(curl, CURLOPT_URL, "rtsp://rtsp.example.com");
    result = curl_easy_perform(curl);
    if(result == CURLE_OK) {
      long cseq;
      curl_easy_getinfo(curl, CURLINFO_RTSP_CSEQ_RECV, &cseq);
    }
    curl_easy_cleanup(curl);
  }
}
