NAME

CURLINFO_RTSP_CSEQ_RECV - get the recently received CSeq

SYNOPSIS

#include <curl/curl.h>
CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_RTSP_CSEQ_RECV, long *cseq);

DESCRIPTION

Pass a pointer to a long to receive the most recently received CSeq from the server. 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.

PROTOCOLS

EXAMPLE

int main(void)
{


  CURL *curl = curl_easy_init();


  if(curl) {


    CURLcode res;


    curl_easy_setopt(curl, CURLOPT_URL, "rtsp://rtsp.example.com");


    res = curl_easy_perform(curl);


    if(res == CURLE_OK) {


      long cseq;


      curl_easy_getinfo(curl, CURLINFO_RTSP_CSEQ_RECV, &cseq);


    }


    curl_easy_cleanup(curl);


  }
}
