CURLOPT_RTSP_SERVER_CSEQ(3)

💅 CURLOPT_RTSP_SERVER_CSEQ 💅

okay so bestie, this is a page from the libcurl manual — specifically the CURLOPT_RTSP_SERVER_CSEQ(3) one, aka Library Functions Manual energy. sit down, grab a strawberry drink 🍓, and let's get into it.

---

✨ NAME ✨

CURLOPT_RTSP_SERVER_CSEQ — the RTSP server CSEQ number. yes that's the whole name, she's long but she's iconic 👑

---

🌸 SYNOPSIS 🌸

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_RTSP_SERVER_CSEQ, long cseq);

---

🦋 DESCRIPTION 🦋

so you pass a long in there to set the CSEQ number to expect for the next RTSP Server to Client request. that's the vibe, that's the whole job. 💖

⚠️ NOTE: this feature (listening for Server requests) is unimplemented. ngl bestie, it's giving "placeholder in the group chat" 😭 the option exists, the listening part does not. don't come for me, I'm just the messenger.

---

🎀 DEFAULT 🎀

0

(the default is literally zero, she starts from nothing, we respect the humble beginnings 💜)

---

🔥 PROTOCOLS 🔥

this functionality affects rtsp only. like, rtsp and nothing else, no cap. 🫶

---

⭐ EXAMPLE ⭐

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode result;
    curl_easy_setopt(curl, CURLOPT_URL, "rtsp://example.com/");
    curl_easy_setopt(curl, CURLOPT_RTSP_SERVER_CSEQ, 1234L);
    result = curl_easy_perform(curl);
    curl_easy_cleanup(curl);
  }
}

see how she sets the URL, sets the CSEQ to 1234L, performs, and cleans up? main character behavior, honestly. so tidy. 🌈

---

🧚 AVAILABILITY 🧚

added in curl 7.20.0 — she's been around a minute, a true veteran 💅

---

👑 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, so go check libcurl-errors(3), iykyk.
